not from Buffalo, but I have a thought...
Walmart has the ship to store thing on their website, and even if they don't have the product in the Buffalo store you can likely order it on the website and have it shipped to the store in Buffalo for in-store pickup.
Also, the suggestion of Michaels or AC Moore seems like a good one (or even Joann Fabrics), see if you can find an online printable coupon or buy a Sunday Paper in Buffalo for a 40% coupon in the Michaels Flyer (though possibly Cri-Cut might be one of the exceptions).
