searching for "landseka" or the Big B

I was reading through an archived post from Dec 2010 and 'landseka' made the following entry:

"Hi Rory, since I bought a bbq liner from the Big B ($13) I leave the cast iron plate home now! I cut it to fit and use it to cook marinaded meats on, fry eggs etc. It even gives the nice 'scorch' marks on steak & bangers just like the bare grill plate."

I'm sure for most of you this will be obvious, but my question is what is the Big B? Is it BCF store?

Thanks!
