Hi Dave,
Yes, buying in stock will involve needing space for storage, and that is one of the things you will have to weigh up when developing your business.
Perhaps a friend can lend you a corner of a garage to store a pallet for a few weeks, that type of thing.
Yes, having stock delivered will also had to your budget, but the idea is of course that you will be making enough margin on the products at retail to come out in front.
Of course that's always the aim......may not always happen, but that's where experience in this business is worth its weight in gold
