I'm rebuilding my LEGO basic brick inventory, and the Pick A Brick wall is just a fantastic resource :) I am fortunate enough to have two Lego stores nearby (one that I pass by every day) and have been getting one or two large PaB cups per week. My piece counts have been pretty low because I am mostly stocking up on 1xN bricks in various colors (white, light bley, tan) for my new city, and also foliage and any tiles I can find. I will probably switch to more specialized pieces once I feel my stock of basic pieces is sufficient.
