This has popped up on a couple of my recent purchases of bicycle components offering to give me some money in return for registering as a member. What I really don't like is that they want your credit card info. Now they aren't a threat of any sort since I checked them through the Google site that checks sites for malicious software or any reported problems. But I'm certainly not spreading as important as my credit card information to the seven winds. I'm nervous enough about Paypal. Has anyone else had any contact with them and if so what?
