Latest coupon and price update (UTC):
X13 Pro Metal Detector TIANXUN High Sensitivity Metal Hunter Gold Digger Treasure Hunter Depth 2.5m Finder Metal Detector
Banggood ($235.99)
Banggood warehouse is located in China. Hmmm… There is no active coupon in Banggood at this moment. You probably want to know if this is a good price. According to my database, the average price is $239.79 and current price is $235.99, so it’s probably a good price!
