Welcome to the board. A word of warning, it is addicting.
I usually buy whatever I want depending on price and availability. To start a stash though I would suggest at least one yard pcs. If it is a really good sale, then 2. And once you become a regular, you willbe able to buy on this board and there are great buys offered by other members. Warning again...you will spend money on here. The 12 step programs for withdrawal do not work on this board. LOL
