"now accepts Bitcoin"

Sheetz has has used Flexa for years. Flexa is a KYC and custodial app where users can load in Bitcoin and shitcoins. Flexa sells those for fiat on-demand and sends that to Sheetz. They are not accepting or receiving Bitcoin.

Only the discount is new.

I'm guessing that Flexa is subsidizing this promotion since the Paypal product just announced is a copy of their business model.

Unless I can scan a QR code and send Bitcoin from my wallet, your business is not "accepting Bitcoin".
