restocking your preferred item(s)

Suppose your local grocery, or mass market store (WalMart, Target) is out of your preferred item (household cleaning product, personal care product, laundry product) and the stores you're willing to drive/walk/take the bus to don't have it either. You look every time you go to your usual store, but they don't have it for a few weeks and you're close to running out.

You don't want to get it online for whatever reason (it costs more online, don't want to pay shipping, website is a pain to navigate) & you hope they restock soon.

After a month or so they finally have it in stock, do you buy more than one in case this happens again?

Not like a dozen, but two or three?
