Buds prices are set by a computer program here is what buds has to say about them From Buds “Our website updates every 20 minutes, 24/7, with our current inventory and replacement cost. We do not price our guns manually based on our cost in each, rather we use a live download from manufacturers and distributors to set our price based on our current replacement cost. As our cost changes, the corresponding website price of each make/model will change up/down accordingly. Although our profit margin remains unchanged, our advertised prices will change frequently, sometimes several times per day.”

Corey, this is strictly a stock level issue. Buds prices are tied directly to stock level and there are more of the higher capacity model in stock than the much lower stock 10rd model.

Bud's prices are based primarily on 'replacement cost' of buying another of the same item from the manufacturer. Here is their explanation of how their prices are set, copied directly from Buds web site: “Our website updates every 20 minutes, 24/7, with our current inventory and replacement cost. We do not price our guns manually based on our cost in each, rather we use a live download from manufacturers and distributors to set our price based on our current replacement cost. As our cost changes, the corresponding website price of each make/model will change up/down accordingly.
