The above says it all but to fill out the form I'll run off a few more mindless platitudes ...
Firstly the system is friendly enough not to need any guide but here goes...
Buying look at the picture, they are worth a thousand words, then read the description! If in doubt ask the vendor, don't assume anything!
Check the vendor restrictions. Do your research before you start bidding! You can only blame yourself if you pay more then the item costs down at your local retailer! Don't get carried away... Hey competing is fun but don't win at any cost... that's real money your bidding with!!!
Know when to drop out of an auction! Check your typing... then check it again... before hitting the return key!
