Rexing has a $10 off sitewide coupon for orders of $199 or more listed at the top of the page, and that coupon is best for shoppers whose cart just clears the $199 threshold and who want a straightforward fixed saving. The page also shows a site sale with up to 55% off selected products, which is a better choice when the item you want is part of the marked down selection.
If your cart is under $199: you cannot use the $10 off coupon because it needs a minimum order of $199. Look for sale items instead. For example, if the dash cam you want is included in the up to 55% off sale, the sale price will usually save more than any fixed amount; buy that marked price. The specific model sales listed, such as 43% off the V5C or 38% off the S3, apply directly to those marked products.
If your cart is $199 to $199.98: the coupon still does not apply until you reach $199. On a $199 example order you meet the $199 minimum and the $10 off coupon can be used. On the other hand, if the single product you want is the REXING CPDuo Pro at the marked price of $199.99, that deal already gives you a specific price of $199.99; compare the final totals for your decision.
If your cart is $199 or more: the $10 off coupon above applies and takes $10 off orders of $199 or more when you enter the promo at checkout. For example, on a $250 regular price order, the coupon takes $10 off, leaving you with $240, a $10 saving. If one or more of the items in your cart are part of the up to 55% off sale, that marked discount usually delivers a bigger saving than $10 on the same item; use the sale price when available.
If you are buying a single marked product on sale: use the product specific sale price. For example, a product originally $300 but offered at 55% off becomes $135, saving $165 compared with the original price. That will beat the $10 coupon for the same item. For the V5C at 43% off, or the S3 at 38% off, use the prices as marked for the larger percentage savings on those models.
Our record context: we list 13 offers for Rexing in the 12 months to October 2026, and the biggest percentage sale we have seen in that period was up to 75% off in November 2025. Our records show no team checkout tests for this brand in the 12 months to October 2026.
To choose between the $10 coupon and a percentage sale, calculate the cart total as follows: start with the original prices, apply any marked sale pricing shown for selected products, then compare that result with applying the $10 off coupon to a $199+ order. Take whichever leaves you with the lower total. Only use the $10 off coupon when your pre coupon cart meets the $199 minimum and the sale price on a desired item does not already cut your total by more than $10.
