That is what Sears tries to do (only let you order online for immediate pick-up until they think inventory is down to 1 in that store). But in the last few months they have increasingly been making mistakes due to what showed up on the truck not matching what got loaded into the system for that truck (they don't actually inventory what they take off the truck in the store), and/or intentionally omitting substantial quantities of certain items from ever being able to be ordered online. And there are a few items in-store that aren't even listed online.
Oh no, I hope not! Those are nice sturdy boxes. You never know with Sears, they could be back to normal shipments of these in a month, or they could disappear forever.

All already gone in my store according to the website, will have to check in person to be sure.
