I usually spend at least an hour a day on ebay, half of which is on HL's. I've gotten about 15 HL's through ebay and there's a lot I take into consideration when bidding.

First, the shipping amount. Some sellers want $12.00 to ship a piece. If it's a current piece, I can buy it on the internet with no shipping or tax charges. The auction amount has to be at least $15.00 lower than the store price to make it worthwhile.

Second, if I can use a credit card, I am more apt to pay a higher price.

Third, I've learned the names of the sellers who use a high reserve price. I've learned to ignore those auctions because the price will be too high.
