Online crafting stores will vary, but many do offer price match programs. Even so, the price match process for craft stores online will be far more arduous than that of a brick-and-mortar store.
For example, in order to receive the online price match you’d have to call their customer service line to place the order.
Price matching in brick and mortar stores is much easier. All you’ll need is proof that the item is identical and a way to show it via website, flier etc.
Major brick and mortar shops like Hobby Lobby, Michaels, Joann’s and Dick Blick all offer a price matching program.
