ThinOptics' headline offer is 20% off sitewide with some exclusions, which works well for most shopping trips. However, several other discounts are running at the same time, so the best choice depends on what you're buying and how much you spend.
Small orders under CA$50: If you're picking up a single pair of readers or a case, the 10% off sitewide deal will apply to your basket. That's the automatic discount available to you at this price point, saving you CA$5 on a CA$50 purchase.
Orders from CA$50 to CA$100: This is where the 25% off all best selling readers, cases, and prescription eyewear becomes useful. If your basket is made up entirely of these items—say, a pair of bestselling readers plus a protective case—you'll save 25%, which beats the 20% sitewide offer. On a CA$80 basket of eligible items, that's CA$20 back instead of CA$16. Check whether your specific products are listed as "best selling" before relying on this one.
Orders over CA$100: The 20% off sitewide deal becomes your go to option for most purchases. On a CA$150 basket, that's CA$30 in savings. However, if your entire order consists of best selling readers, cases, or prescription eyewear, the 25% off offer is still the better choice, saving you CA$37.50 instead of CA$30.
During the summer sale period: ThinOptics runs a summer sale with up to 30% off sitewide, which will beat all other offers when it's active. This is worth checking for, especially on larger orders.
First time customers: If you're new to ThinOptics, signing up to the newsletter will get you access to special offers and promotions going forward. You might receive an additional first purchase discount this way, though you should check what the newsletter sign up actually unlocks before relying on it.
Only one offer applies at checkout, so compare the final discount your basket qualifies for and take whichever saves you the most money. The percentage deals will always beat the fixed percentage offers on larger purchases, so do the maths on your specific items before you pay.
