Staples $15 off $50 in-store coupon **YMMV**

[Carnos Jax]

That's interesting, because I asked the cashier that, and she said no, I can apply it anything, in addition to stacking it on top of other coupons (that normally wouldn't be able to be stacked). Maybe she just didn't know the rules well enough.

I pulled out the ink cartridge and she gave me the coupon on the spot as I was buying the burner.
