What Am I Not Comfortable Buying Online?

I feel that I am comfortable buying pretty much everything online.  I have bought all kinds of things online:

• car parts
• halloween costumes
• jewelry (as gifts, not for me)
• software
• books
• hot sauce
• viagra

Ok, not viagra.  No really, I have a few more years before that might spark my online purchasing interest.  I figure that if im relatively safe using my credit card, as it has a 500 dollar built in limit on fraudulent charges. 

I am more disinclined to shop online because it is soooo easy.  Talk about impulse buys.  I could very easily rack up some serious charges online.  I have done so in the past.  Talk about a spending hangover!  

Do I fear online fraud?  Not really.  I am more afraid of crushing consumer debt.
