So far:
Call center guy says his system shows I was only charged the proper 6% state sales tax, not the 18% that showed up on my final invoice after I gave them my CC info and hit the final "buy" button. He also told me yesterday my total cost is the discounted total I had after the initial 3 codes at the beginning of the thread. I ordered around midnight, technically Thurs AM. Got an "order shipped " email yesterday PM for the strings that I ordered to make my total over $350. They shipped USPS, so there's no telling if/when they will show up.
Today the amp shows "shipped," I have a UPS tracking # but it is not working yet. In my experience it can take a while for a tracking # to become usable on their tracking site. My credit card has been charged $20.
This is more than the discounted strings price, but less than the normal GC selling price for these strings.
Like Towelie says, I have no idea what's goin on right now.
In other news, I did just get the Midi Merge (combines 4 inputs into 1) I ordered before this whole mess began. They sent me a Thru (splits 1 out into 4) instead. Exactly the opposite of what I need, and much cheaper than the one I paid for. Wonder if they'll send the right amp, if they send it at all?
