I timed out on the edit, so I'll add it as an additional reply. Sorry for taking up so much space, just wanting to help you out:

EDIT=additional information When it comes to having a new item posted, set the initial high, but have it on sale for a month. You will get more sales in that first month because people have something to compare the sale price to. This will also allow you to see if this item is profitable, and you may see how pricing effects people's buying habits.
Or, set a high initial pricing in one market for the new item with a sale price, and sell it also at another market at the intial price set at the sale price (but not on sale) and see what occurs. You will more than likely (based on statistics) get more purchases on the sale price than the same item with the initial price set at that same sale price. If you have ever worked for either a retail or grocery store, they use this same method.

I work for a Fortune 500 company (intimate apparel division) and that's what we follow on new items. We market a new item at (let's say) Wal-mart with a low initial price. We also market this new item at (let's say) Goody's at a high initial price, but compromise a sale that is set just a few cents below Wal-mart's initial price which is not on sale. We find that Goody's sells more of that item, and after a few months, the item is discontinued from the Wal-mart stores. The purpose is to see the consumer's buying habits. If people continue to buy the item at the high initial pricing at the store that previously had the sale, we discontinue the item at the low-end store. But, if we see a profit being made at the low-end, we drop the high-end and up the price a percentage and sell it till we discontinue it after a few months to a couple years.end EDIT
