This is J has plenty of ways to save, with the headline being the 10% off promo code at the top of this page. This code works on any purchase at checkout and is reliable for a quick saving on everything from loungewear to accessories. Beyond the code, you will find bigger discounts on specific products and sitewide sales that may beat it depending on what you are buying.
Building a small cart under CA$100. If you are spending less than CA$100 on items not covered by dedicated product sales, the 10% off promo code gives you a straightforward saving. On a CA$70 order, for example, the code brings your total to CA$63, saving you CA$7. First time customers should check whether the 10% off first purchase code provides the same or better value, though both codes offer 10% off, so the result is the same. New customers who have not yet bought from This is J can also sign up to the newsletter for future promotions, though no immediate discount is advertised with that signup.
Shopping for specific loungewear sets. If your cart holds six loungewear separates, the 20% off loungewear deal applies automatically when you add six items, bringing much steeper savings than the 10% code. On a CA$120 order of six loungewear pieces, this deal would save you CA$24, bringing your total to CA$96. However, this offer cannot be combined with other discounts, so you must choose between it and the promo code. Similarly, if you are buying the T-shirt and short set, the 25% off that specific product applies. On a set priced at CA$48, you would pay CA$36, saving CA$12. The Relaxed Long Sleeve Set has a fixed CA$36 saving, which works better on higher priced versions of that set. Again, these product specific deals do not stack with codes.
Looking at men's lounge shorts or Tulip Shorts. The 35% off men's lounge shorts and 13% off Tulip Shorts are dedicated discounts that apply directly to those items. On men's lounge shorts at CA$60, the 35% off brings your total to CA$39, saving CA$21. These fixed product deals typically beat a percentage code when applied to their specific items but cannot be combined with other offers.
Browsing sale or already reduced items. The 20% off sitewide sale, the 10% extra off sale styles, and the up to 30% off season styles all apply to reduced or seasonal items. On a CA$100 order of sitewide sale items, the 20% off sitewide saves you CA$20, leaving CA$80 to pay. If those items are already on sale and marked down further, the 10% extra off sale styles applies on top of the existing markdown. For season styles marked at up to 30% off, select items qualify, so you get up to 30% back on those pieces only.
Our records show that This is J listed 107 offers in the 12 months to October 2026, with percentage codes typically around 10% off. The largest percentage sale in that window was up to 80% off in December 2025, so the current landscape of 10% to 35% product specific discounts is in line with what the brand usually runs. Our team tested four codes across the year and confirmed all of them worked at checkout.
To get the best deal, work out which offer applies to your items, then compare the final totals. If you are buying a specific product with a dedicated discount like the men's shorts or T-shirt set, use that. If you are stocking up on six loungewear pieces, take the 20% loungewear offer. For everything else, the 10% off promo code at the top of the page will give you a consistent saving, unless a sitewide or seasonal sale already brings the price down further, in which case check whether the extra 10% off sale styles or the sitewide 20% would leave you with a lower total.
