Last month, I picked up a J.A. Henckels 10 Piece Forged Knife Set at Costco for $139.99 after an instant rebate of $30.00. Of course, unless you are actually tracking prices, you cannot tell whether the post-rebate price is a good price. Did the seller raise the price and then offer a rebate for difference? After the rebate expires, will the new price be the old post-rebate price?Well, at least for this item at Costco, once the rebate expires, the sales price reverts back to $169.99.
