Pretty much, but you'd probably want to scan your SB QR code when you have them scan your BB rewards card. SB is just another rewards program, like BB rewards, so I do both at the start of the transaction so I don't forget one or the other.
I have them scan things in this order:
- Rewards program(s)
- Items I'm buying
- Payment
But as long as it gets added to the receipt before payment then you should be ok. You'll see it print on the receipt towards the bottom as "Hardware/Software, You purchased the following: SWAGBUCKS $0 AFFLIATE SKU, Shopper ID: xxxxxxxx" if it all worked correctly.
