Personally, I would NOT use Craig's List. Why? Because you have to meet the person and that is just not safe. I have sold many things on Ebay and it is safer in that you receive payment through PayPal and if you should encounter any problems, you don't have to figure out how to fix it on your own. Ebay will step in and that in itself is safer and easier. First, you will have to create an Ebay account. Choose a password that is SAFE, meaning it's not something easy like a birthdate. Include letters and numbers and special characters if possible. Your user name will be seen by buyers, so choose it carefully...nothing personal. It's very easy to create an account with Ebay, the instructions are very clear. A digital camera is a must! You will need to include a photo of the item you are selling and use a solid color sheet (fabric or wall) as a backdrop for your item. Ebay allows you to post one free picture and if you need to include more than one, there is a fee. In fact, there are fees for lots of "extras" that you really don't need. You don't need fancy lettering, bold letters, etc. Utilize what Ebay offers for free to your best advantage. You pay a listing fee and whatever your item sells for, there will be a fee for that as well. Be as descriptive as possible in your description of your item. Be truthful and very honest. If something has a flaw, no matter how minute, make that known in your description. Honesty is the best policy. Buyers are going to give you feedback after the transaction and this feedback is going to allow future buyers (or repeat buyers) to decide if you are worthy of doing business with. It's been a while since I've sold on Ebay but last time I sold, they were in the process of eliminating sellers from accepting checks for payment. Do yourself and buyers a favor: ONLY use Paypal. It's safe! You will need to create an account with PayPal as well. It's also free to sign up and you don't need the fancy accounts they offer. Just the basic one for buying and selling on Ebay. Again, the instructions are easy. You will need to provide your checking account number I believe, or perhaps a credit card number. You provide this info because this is how they prove who you are and in the event you don't have funds in your Paypal account from a previous sale to pay for the fees (Yes, even Paypal has a fee, but it's minimal), they can take the fee from you checking account. You can leave your funds in Paypal for as long as you want. I usually transfer the funds to my checking account once I get to a specific dollar amount but the moment you get paid, you can go to Paypal and do a transfer. The transfer for Paypal to your checking account is easy and usually takes places in 24-48 hours. There is NO fee to transfer from Paypal to your checking account. I do believe you can ask Paypal to issue a check to you, but if I remember correctly, there is a fee for that.
Once you list your item on Ebay, it will stay listed for 7 days. You can check your item daily and see how many people have looked at your item, you can see how many are watching it, and you can see who and how many have bid on it. It's so easy, you will be amazed! It's been at least 8 months since I've sold on Ebay so I know there have been many changes but I think you would prefer Ebay much better than Craigslist. Also, make your shipping charges fair. Ebay allows you to add a handling fee to your shipping charge (I usually add $1.50- $2.00). I've seen crazy shipping charges. Offer shipping choices for your buyers, too. I don't offer UPS or FEDEX but only through the post office, and you will want to make this known in your description. I offer Priority and Parcel Post, and media mail if possible. I would strongly suggest that you include insurance and delivery confirmation on all of your items (find out how much those cost and add them to your shipping price that you will charge your buyer). The last time I sold on Ebay, my buyer emailed me 2 months after the fact to tell me that he had not received his item. I contacted Ebay and they told me that the buyer should have contacted me within 7 days of the shipment notice I sent to him. Basically, there was nothing any of us could do but at least with insurance and delivery confirmation, I could have shown when the item was delivered. There was no recourse for any of us and the buyer, luckily for me, was not disgruntled about it. Ebay told me that I was not under any obligation to refund anything because the buyer failed to follow proper procedure. So you can see why Ebay is better. They will respond and help you resolve an issue, should one arise. You can contact me again, for additional information if you'd like. There are crooks on Ebay, unfortunately. I've had an incident with a foreigner who was offering me way more money that my auction was for. Again, I contacted Ebay and they concluded that the person was a fraud. ONLY communicate with buyers through the Ebay notification system. At no time should you ever give your personal email address to any buyer. IF anyone asks, you should report them to Ebay immediately. I've sold tons of baby items on Ebay. You will do very well with those items without a doubt. Also, if you have consignment shops in your area, that is also a really good way to sell items fast and easily. Consignment shops usually pay you 1/2 of what the item sold for. Most shops have a consignment period (2 or 3 months) and at the end of the period, you can collect your unsold items or donate them to a local charity. Some shops allow you to collect your money before the end of the consignment period, others make you wait until the very end. I've done very, very well with consignment shops as well.
Another thing with Ebay, in your description, let your buyers know when you intend to ship. For example, I inform my buyers that I ship within 24 hours of a posted payment to Paypal. The only exception would be a weekend or holiday but I make that known. The day I ship the package, I let the buyer know through the Ebay email system and if you have elected to charge them for delivery confirmation and insurance, I include those numbers to the buyer...that way they can track it too...and it proves to them you sent it when you said you would.
