You can have 5 variables in your eStore, meaning, a mixture of colors, artwork designs or apparel items. Example: 1 design offered on a t-shirt with 2 shirt color options and also offered on a long sleeve t-shirt with 2 shirt color options is 5 variables. Based on previous customers- I would limit the amount of products the first run to see how many people actually order. We suggest on keeping the amount of designs and products to a low amount of 1-2 per campaign. The more designs you may offer often will lower the order total for each design which will make your final cost of those designs higher. The higher your cost, the lower profit a school makes. We suggest running a campaign for about a month with 1-2 designs and if you want to offer additional designs, reopen the eStore and run a new campaign the following month. This has shown the best results. Often a family only wants to spend X amount in a month on school apparel. They may like each design but are not able to buy each one all in one month.
