We require a minimum order of $25 for all orders that are shipped. The minimum is to help you and your business, because shipping orders under $25 are not viable. The shipping cost to product cost begin to eat at your profits.
For example, Buying $10 worth of merchandise and shipping it for a minimum of $5.00 raises your cost for those items by at least half.
This is the reason for the $25 minimum on shipments.
