Not sure where to post this, so please read on...mods, please move as appropriate. I was looking at a little guitar combo amp (Acoustic Lead Guitar Series 20 watt) earlier today on guitarcenter.com on my iPad. A strange popup in Chinese appeared. I clicked "show in English" and it said something about International shipping being available. When I dismissed the popup, the price of the amp increased by 20% from $69.99 to $83.99 before my eyes! (Price at MF is still $69.99.) A bunch of other prices on the GC page increased simultaneously. Then later I tried to compare the Fender Frontman amps on GC and MF sites. Earlier they were featured on both sites. They are still offered at MF at the same prices, but show unavailable at GC. Is this the tip of some iceberg of differential pricing? Is Fender cracking down on GC for some reason? Has anyone seen a similar pattern when shopping for deals on bass gear between the sites? SL Edit: The mystery deepens. On a hunch, I cleared the cache and cookies from Safari on the iPad. Voila, prices back to normal with only minimal discrepancies between GC and MF. Fender back in stock at GC. .??? Weird indeed. Guess the prices depend on where the site thinks you are located. FYI.
