Was surprised when doing my fall oil and filter changes that Walmart didn't have any Rotella T6 or filters for my bikes, and no 10W40 or filters for my trucks. Luckily, I had plenty of everything in my stock, but it was strange that their shelves were pretty much empty. I don't usually take anything out of my stock unless I can replace at the same time. This is the first time in years that I popped anything out of the front of the queue without pushing anything into the back.
One thing's for sure, shortage translates to higher prices. Can't see supplies being totally shut down as long as the sellers can set the prices as high as they like.
Luckily, food supplies at the wholesale grocery I buy from seem to be fine. Plenty of rice, beans, and eggs at a good price, and what doesn't anyone really need other than that?
