I have been trying to create a spreadsheet to predict store size needed to sell x amount of product. If my calculations are correct, here is what I come up with. If a person was wanting to sell 15 items per day and they had a 100% STR, they would only need 1375 items in their store to achieve this.
@ 75% STR they would need 1830 Items
@ 50% STR they would need 2750 Items
@ 30% STR they would need 4575 Items
@ 20% STR they would need 6900 Items
@ 15% STR they would need 9200 Items
How big is your storage area? Is it worth it to bring home Higher STR items? I think so.
