My cert was for $5. I ended up price matching Red Faction Guerilla Remarstered for Switch at $20 (from Gamestop's sale) and used the $5 cert to buy it for $15 at Best Buy.
Thank you so much for this $30 off $60 link! I used this deal and the prime 20% discount to pre-order Super Smash Brother Ultimate for $18 + tax!
I also used the 20% off rewards/points offer + the prime 20% discount to pre-order SNK 40th Anniversary for $24 + tax.
Thanks OP! I bought 2 South Park TFBW for Switch and traded 1 into Gamestop for $32.50 towards Smash Brothers ($27.50 credit with Pro card plus $5 bonus towards the pre order of any game). I'm happy to get South Park for about $30.
