On some big events such as Black Friday, Valentine's Day,... mechdiy will constantly offer up to 50% discount or more, so all customers can purchase well on their budget without worry.

To use the mechdiy coupons on their website, you need to meet the conditions:

•  The items you choose must meet all coupon requirements as explained in the Terms and Conditions.

• The coupon has not expired. 

• The seller uses the mechdiy checkout system or a customized checkout system that accepts the coupon.

It depends! Normally, the percentage that you can save with that mechdiy Coupon will be shown right on the page, so you can see if it is applied sitewide or not. However, once you are not sure, try it right on their's products you want to buy.

Usually, Coupon Stacking is not allowed at mechdiy. However, the store will surely give out notice if available.

There are now 2S offers on our site and mechdiy Coupon Codes usually end in 3-4 days. However, some mechdiy Deals don't have a definite end date, so it's possible that the code will be working until the store runs out of inventory for the promotional item.
