Just got back from Best Buy to have them price match (because I'd already bought it there and reward points, right?).
1st lady said she couldn't do it because it wasn't their website price. She called a manager (I didn't ask for a manager, she just took it upon herself).
I explained to the manager that it was their in-store price and showed it to them on brickseek. I even offered to go buy and return it at walmart so they could do it off a receipt if need be. Manager said she couldn't do it off that website because it wasn't official, but said "give me a minute", walked in the back, then called back up front on the walkie talkie that if I called Walmart on the phone and asked them, they'd match it.
Well I knew calling walmart was a futile attempt, but I was already there... So I called Walmart 3 times (electronics, no answer; customer service, no answer; electronics again). 10 mins on the phone with no answer, just ringing until it hung up.
1st lady had to leave; her shift was over. Passed the process over to some younger kid who was like "IDGAF" and said he'd price match it asap. Cool. Except he couldn't, because of some issue with the bundled steel book. IDK. Anyways, he went and got a different manager, who finally price matched it. Only took like 45-50 mins for $10.
TLDR: Got it price matched at Best Buy.
