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.

Hi and welcome. This is due to number of each in stock. Buds prices are tied to stock level and higher stock same or similar items will be lower priced than same or similar lower stock items and vice versa. Cheers and stay safe!
