At AliExpress, the Garmin Forerunner 255 drops to $240 with promo code “AFFUS40”. This is a great deal for a new model, as you’d pay around this for a refurb at some stores, including Amazon. This watch introduced a dual-frequency GPS system that uses multiple satellite signals at once, a feature Garmin had previously reserved for its pricier Fenix and Epix watches, and it noticeably improves location tracking in cities and under tree cover compared to standard single-frequency GPS. The watch ships free, too. The coupon ends on October 31. Buy Now at AliExpress
