Thumb Score: +1
Costco.com has Rocket League Collectors Edition for Nintendo Switch (physical cartridge) for $ 34.99 + $ 1.99 shipping. Not sure if it’s available in stores and at the same price to avoid shipping and make this a better deal.
YMMV for price matching.
Very YMMV: I mentioned to Amazon chat that I didn’t see the 20% off new releases (can show them Best Buy product page for 1/16 release) for this particular game and I was given an $ 8 credit.
