Fytoo runs a 15% off coupon code for prescription glasses alongside a range of fixed dollar discounts and a buy one get one 50% off frames promotion. The 15% off code works best on higher priced eyewear purchases, while the fixed discounts and sale promotions give better value on smaller baskets or specific items.
On orders under $50. If you are spending under $50, the 10% off code for orders under $10 applies only to very small purchases. For most shopping below $50, the $6 off coupon code for orders over $50 cannot be used, so check whether the flash sale or clearance items cover what you need, since those may deliver bigger savings than the percentage codes available to you.
On orders $50 to $79. The $6 off coupon code for orders over $50 gives you a fixed saving. Compare this with the 10% off code on your specific order. On a $70 basket, for example, the $6 off code saves you $6 to leave $64, while 10% off saves you $7 to leave $63. The 10% off code wins here, so use that one.
On orders $80 to $119. The $10 off coupon code for orders over $80 and the 10% off code both apply. On an $100 order, the $10 off code saves $10 to leave $90, while 10% off saves $10 to leave $90. They are equal. At $110, the $10 off code leaves $100, but 10% off saves $11 to leave $99. The 10% off code edges ahead on larger baskets in this range.
On orders $120 and above. The $15 off coupon code for orders over $120 becomes available. Compare it with both the 10% off code and the 15% off code for prescription glasses. On a $150 order, the $15 off code saves $15 to leave $135, the 10% off code saves $15 to leave $135, and the 15% off code saves $22.50 to leave $127.50. The 15% off prescription glasses code wins. On a $300 order, the 15% off code saves $45 to leave $255, so it remains the strongest choice on glasses within its selected styles.
On frames. The buy one get one 50% off frames deal applies only when you add two pairs. The discount goes to the cheaper pair. On two $100 frames, you pay $100 plus $50 to leave $150, a saving of $50. Compare this with the 15% off code, which on $200 frames saves $30. The buy one get one promotion wins here. The deal does not apply to frames under $10 or lenses and coatings.
Choosing between offers. Work out what you are spending and which offer applies to your basket. If multiple offers are available at your spend level, compare the final total: the 15% off code for prescription glasses saves the most on higher priced eyewear, while the fixed dollar codes give better value on smaller purchases and the buy one get one frames deal beats both when you are buying two pairs. Note that only one coupon code can be used per order, so you cannot combine a discount code with another code, though you may find the flash sale or clearance items worth checking for even lower prices on selected products.
