Thanks for all the input - I found a cheap source that I will share for the 3MM There A+ sinking (2,000gm for 48.99) and 4.5MM Float XL (1,600gm for 41.99). I got it from 1800PetSupplies.com - free shipping and no taxes either. It was delivered fine and the food was fresh - one expires Dec, 2019 and the other Jan, 2021. My only concern was that Thera A+ was listed at 2,270gm, which I thought might not be correct - it was only 2,000gm.
