Shortly after my first purchase from a popular CC vender it seems the info I used to sign up was spammed to a bunch of common sites (Amazon, Ebay, etc) and I got notifications from those sites that there were attempts to change my password and info. I had to call each of the sites' customer service to discuss the accounts as my email contact, password, etc were changed by someone to crazy things.
I already contacted the vender and am certain the breach came from their end as I have not used that login/password combo in a long time (which is a good thing). After speaking to them they are looking into it and they did show genuine concern. I do not think the company is intentionally selling data but perhaps they have a bad egg working for them?
Regardless, I just wanted to make a public service announcement that it never hurts to use different logins and passwords - especially with international sites - and always use different logins for your bank, stocks, etc than you would online purchases.
[mods I reviewed the rules and I dont think this breaks any as far as I can tell]
