Mr Key Shop runs several percentage discounts across different product categories, with the Back To School Sale offering extra 15% off sale products as the page's main promotion. The other deals target specific software categories or offer broad catalog discounts, so which one saves you the most depends on what you're buying and how much you plan to spend.
Buying from the sale section during back to school season? The Back To School Sale with extra 15% off sale products is your best bet, since it stacks on top of the existing sale prices for extra savings.
Shopping for Microsoft Office 2021 licenses? You'll want to compare: the 10% off entire catalog deals against the dedicated up to 60% off Microsoft Office 2021 licenses offer. The Office specific deal is clearly superior here—at up to 60% off, it will save you significantly more than any general 10% discount.
Looking at Autodesk products? Check whether you need Autodesk Commercial software or general Autodesk products. The up to 65% off Autodesk Commercial offer beats the 30% off general Autodesk products, so grab that one if the software you want falls under the commercial range. If you're buying regular Autodesk (not commercial), the 30% off is your dedicated option.
For Microsoft Windows 10 Home specifically? The extra 10% off Windows 10 Home beats the general 10% catalog discounts since it's a targeted boost on top of any existing pricing.
Shopping everything else or mixing categories? The extra 10% off everything offer or the regular 10% off entire catalog deals are your general fallback options. These work across any non-discounted products in the store.
First time customer? Consider signing up to the newsletter for special offers and promotions—this could unlock additional deals beyond what's currently listed, though you'll need to check those terms at signup.
Since only one discount applies at checkout, add your intended purchases to your basket and compare what each relevant offer would save you. Specialized deals (like the Office, Autodesk, and Windows 10 Home offers) almost always outperform the general 10% discounts on their category, so choose the deal that matches your specific product rather than reaching for the broadest option.
