I think, depending on how the cases are sold, either directly from Amazon warehouse or shipped from TBEVs warehouse and just sold through amazon, but to reduce overhead, not all 5000 cases would be available on the website to be sold. Possibly some are kept in storage for a continuous flow to buyers, atheletes, distribution companies for product testing for future distribution deals, advertisement, etc. Just a guess, but sounds plausible instead of dumping all 5000 cases on Amazon and saying "here ya go!!!"
