using online coupons at B&M

[glagic]

i've never used any online coupons in store unless theyre printable. i was wondering if i could take a coupon code, in this case, for office depot, take it in store and use it on a purchase? or does this only work online or over the phone?

someone help with this? i found logitech z340 speakers and am thinking about getting them, but i dont want to pay full price. can i use an online coupon in store if i give them the code?
