I'm not no manager of retailing but I'll tell you what I know on how to fix your problem. That district manager will be highly impressed when you tell them you found out how to fix your retailing problems.
First, you're going to need approximately 5,000 cubic meters of sand (could be more or less depending on your retails). I'd suggest "Strathcona Sand" which can be purchased at this website:

Basically you are going to want to cover your retail items in the sand in a large container; let it sit for 2-3 hours, then shake it up, take out approximately a third of the sand then start the process over again until there is no more sand left.
Any residual sand left on the retail items after this is done is not to be removed from the retails. It is to remain on the product until it reaches the point of contact with the customer. The customers will start buying more products.
Make sure to charge it to your companies expense account because Strathcona Sand can be highly expensive, but the retails you gonna make afterwards will pay for it in the end and that district manager is gonna give you a raise for saving the company millions.
Let the district manager know this is your game plan and he's gonna be highly impressed.
