i ended up buying 6 bags from the marlboro MA store, they had plenty. i too was going to buy more but in feeling the bags it seemed to be smaller pieces than i am used to getting. however, at $10 per bag a pretty good deal. i have not opened them yet to check sizes. BTW, a full pallet plus available at the marlboro store.
