The ONLY place I've run into a hangup (aside from not having a line of credit), is renting a car. Without a creditcard they put a hold on $400 above and beyond the rental fees. Those take about a week to clear. So if I'm spending $35 renting a car (I've been doing a lot of $20 weekend specials this year since I've had no car, and then it's actually $35 after taxes and fees and extra insurance), I actually need $435 in the bank.
But, no. No cards.
I/we had well over 100k in available credit, and my highest rate was 8%.... 5 years ago. (we had 6 cards; his/ mine/ his school/ my school/ emergencies/ & 0% as long as we used it $50 a month).
4 years ago... Bought my/our house (20% down), and my/our credit score dropped (weird, right? But apparently normal). ANYHOW, because of the drop at least one of the cards lowered my limit below my balance, and charged me 10k in fines. I say at least one, because it was a CRAZY month. By the end of the month universal default EACH card lowered our limit below our balances, and we had 10's of thousands in fines. And our interest rate jumped to 29.99%
In 3 months time, we had over $70,000 worth of debt in money we. never. spent.
Yeah... we were in THAT group of people. The group that got screwed before the laws were put in place to keep that kind of stuff from happening.
Filed for CH13, the courts brought our debt down to what we actually owed before the CC companies got stupid, and I will not willingly have a credit card ever again. I do not trust them. We had near perfect credit (my husband was only 10 points off from perfect, I was 50 points off), never made a late payment, never missed a payment, did everything "right" and got screwed 6 ways from sunday.
Do I occasionally WISH for a card? Durn straight. I've been wearing the same daily disposable contacts for 15months straight (because I need a new Rx time wise -my actualy Rx is probably the same- and the $300 for the appointment and $120 for the contacts is beyond me). I have 12k in lawyers fees to figure out in 5 days. When my dog got sick, I couldn't take him to the vet, and I had to use a cooler instead of a fridge for a week.
$70,000 in debt in 3 months without spending a dime. A bankruptcy on my record. I got SHAFTED by credit card companies a few years ago.
