as a member of ebay for the last couple of months i have larnt alot of things. for example knowing when to stop bidding and knowing how to trust the seller.
the most important thing on ebay is knowing your limits and doing your home work. wouldn't you hate to buy an item that is worth 200 in the shops for 250. you will be really mad at your self. this can create alot of problems for both the buyer and the seller. sometimes the buyer wont event pay the seller coz they paid too much for it. this leads to alot of problems and account cancellations. so one thing is know what is your limit is before you start bidding. and dont get tempted in overbidding, it happens alot.
the second this is knowing how to trust the seller.
Step 1: check the feed back scores. it doesnt sometimes matter if a person has a score of zero they might still be a good seller. the key is asking questions. ask alot of question about the item your interested in. one thing i look at is the speed of reply and if they answer all my questions. if this accurate i qarrantee a good seller.
so follow these couple of steps and you should be fine.
thanks and enjoy shopping
