From Buds FAQ page.
"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."

Alan, Buds prices are in part based on stock level. The lower the stock the higher the price percentage increase. Prices will fluctuate but go back down when stock is replenished. Cheers and stay safe!
