Today's advance research shows no sales with large numbers of glasses going at once, they tend to be sold in lots of 2, 3, or 4; very few sold individually. The good news is that smaller boxes are easier to pack and ship. eBay gets a discount for sellers regardless of the shipper, and I usually ship USPS, but will keep similar sized un-branded boxes handy in case someone wants to ship UPS. (I offer both on my sales.)
I mentioned buying a bag of flour at the dollar store on xmas eve because I was almost out and would have no other time to shop before my family event; that flour was a help but I didn't use much. Since then baking with it reveals that it's pretty awful. Rolls don't rise as well, it's hard to mix into batter (lumpy) even after sifting. The final straw was a deflated batch of dinner rolls on Saturday—I tossed the rolls then tossed the rest of the flour and have Costco organic flour to make more rolls today. Such a disappointment (but the dogs got lucky and each ate a couple of rolls.)
