I can't answer how it was stored but I thought I would give WM home delivery a try. I may be wrong but I would guess the storage for what was delivered is the same as what I would have purchased from the store off the shelf prior to it being loaded on the shelf. Except, the half dozen times I have looked in the store, their shelves were bare. Ordered Friday (two days ago) and delivered yesterday with a date of 153. They charged me $4.63/gal (plus tax) and no delivery charge unless your order is less than $35 then it is a flat $5.99 per order (I believe). I went ahead and ordered enough to exceed $35. Prior to this, I had been buying it at the local grocery store (HEB down here) for a slightly higher price ($4.96 I think) for 7.5% and only 121 ounces.
