I live in a pretty big area (Los Angeles County) and well Best Buy is hit and miss, and here lately a big miss. We don't have a Micro Center that is close and if I was to go to the one in Tustin (Nearest one), I would be looking at an hour drive one way... sometimes longer depending on the day, time, and if there are any events going on along the way. Nope, not going to do it. , and I haven't heard of a Sweetwater, and after a quick search looks like audio gear. We do have Guitar Centers, which I usually shop at for my drum equipment, but I was able to find bass pedal's on amazon at a significant discount. Took it to GC and they did price match it... which they didn't have to do, but they did.
I think your mic stands might have been an ordering issue between the keyboard and chair.
Saying that nicely! I have a feeling there wasn't a lot of research done on what you purchased.
