Calgary MEC may have some really old stock?
About 5 years ago I couldn't find any at Vancouver MEC, nor was it listed online. So I bought three big jars at 3Vets, that'll do me for a while. First one is mostly done.
Just checked, MEC online does not think "sno seal" is something you can buy. Great stuff BTW, but far too economical for any properly managed business to stock. Customers WILL buy something, so only stock the high margin brands. I'm sorry MEC, but the only reason I can conceive of to not carry it is to drive sale of less effective but far more profitable items.
At least the local independent small business (3Vets) still carry it, I saw it there in the spring, so I didn't need to worry and stock up. Not that it goes bad.
