Hack Question

When doing the hack for two different store pick ups how long does it take before they cancel your second item and refund your money? I’d like to get the M18 Blower and the cheapest way right now is the $299 bundle and it drops the blower down to $112. Just not wanting to wait for weeks for a refund if possible. The store near me have made comments about returning the bundle instead of just 1 item when I ordered a combo/free tool last time.
