As Khai notes, if it's for personal non-commercial use only, it's not really the same product, as these products are licenses.

In any case, if you purchased it, you showed how you valued the product. Heck, your own review of the product confirmed that.

Prices are just imputations of value. Whoever buys at the vendor's price agrees to impute the same value to it as the vendor has requested.

We've all bought something and discovered we could have waited and paid less, or bought something else that was just as valuable but cost less. But that doesn't mean we were ripped off; we bought at the price tendered, which sez that it was worth that much to us, after all. If the vendor decides to be extra generous later on, it may make us wince, but it's generosity, not underhandedness.
