tentree's current page highlights an additional 15% off sitewide, which is the headline offer here and works well for most shoppers. That said, several other deals are running at the same time, and which one saves you the most depends on what you're buying and how much you're spending.
Small baskets under $100: If you're spending less than $100, the 15% off sitewide deal is your best bet. On a CA$50 purchase, that saves you CA$7.50. The free shipping threshold of CA$100 won't help you yet, so stick with the percentage discount.
Baskets between $100 and $200: Once you hit CA$100 or more, you now qualify for free shipping, which adds value to your order. Compare the 15% sitewide offer against the free shipping deal in your basket to see which saves more. On a CA$150 order, 15% off saves CA$22.50, so the percentage deal would likely remain your best choice—but run the numbers at checkout to confirm.
Shopping for backpacks or bags: If you're filling your basket with backpacks or bags, the deal on those categories gives up to 40% off selected styles. This could beat the 15% sitewide offer depending on which items are included in the sale. Check whether your chosen bag or backpack qualifies, and compare its discount against 15% off.
Looking at selected styles across the full range: tentree also has up to 50% off selected styles across the whole site. This is worth checking if you're drawn to items already marked down. Again, calculate whether that percentage beats the 15% sitewide option.
Newsletter signup for first time customers: If you've never shopped with tentree before and want to explore more offers, you can sign up to the newsletter for special offers and promotions.
Only one offer applies at checkout, so once you've added items to your basket, compare the savings from each available deal and apply the one that gives you the biggest discount.
