I've noticed this recently, not with food though, with small items being manufactured & supplied from China. There is definitely a break in the supply chain. I've noticed this when I went to Harbor Freight last week, they were out of SO much stuff -- batteries, rechargeable batteries, gloves - almost all types of gloves & they must have about 20 types, in all sizes but only some XXlarge or Xlarge... the worker said they don't know what is even coming in the trucks anymore, they order & there isn't enough stock to fill the order.
I've seen simpler shortages on household items in the 99cent store & dollartree -- & even in home Depot. I tried ordering off ebay the other day, a once common product which i've purchased for years multiple times & they were almost impossible to find & the ones I found were limited on the color & the price was almost double.
The end for cheap goods from China, time for manufactures to return to the States... thankfully, Kodak is the beginning of our drugs being manufactured back here.
