Nice! As much as I love samples, I hate when the accumulate like that and you forget about them. I found a box likes your and since I made a little system. I have a few plastic baggies and labeled them. Protein, stim pre workout non stim pre workout, fat burners, aminos, etc.
Whenever I make an order and get samples, I immediately put this samples in the baggie. I am trying to use them as soon as I get them now as well.
