I ran across this by accident a few years back. Typed in Hobby Lobby and ended up at the craft store. I think they have a small print diclaimer that directs people to the hobby site. We just can't catch a break when it comes to coupons.
You can get some useful stuff from the craft store..... bought a nice Iwata airbrush from the local Hobby Lobby retail store using one of the 40% off coupons. Cheaper than any of the online suppliers, even with the tax..... B)
