You could go through an online portal such as Upromise or Discover and choose store pickup. That will give you 5% or so off the price in cashback. Check evrward for cashback sites. You could possibly even go through the cashback site to buy bb gc. And then go through the portal again to buy the actual item using the GC. I believe the terms say you don't get CB for GC purchase but I have seen it work anyway from Discover for physical BB GC. Also don't need to use Discover cc but they sometimes catch you on that as well. Not sure if you get CB for buying a GC through Upromise. You could try a small amount GC and see if you get it.
