50% off TheMagic5 Swim Goggles (Select Styles) $66 (RRP $133) + $15 Shipping @ TheMagic5

So I was looking for some new swim goggles and noticed on Reddit that TheMagic5 custom made goggles were regularly highly rated in the comments. You 3D scan your face with a phone app and they custom make them for you, Benefits from the comments I read were that they don't leak and you don't have to have them as tight because they fit your face contours so well. https://themagic5.com/pages/how-it-works

Decided I would buy some so started looking into discount codes (as you do!) initially found FB10 and WELCOME10 for 10% off full priced items, then after more searching I found this unlinked page on their website which had the ones I wanted (Blue Magic Mirror Gold) listed at 30% off

Added them to my cart and went to check out, and in the upsell area below the cart where they try and sell you other swimming items like swim caps and snorkels etc, were the goggles I was buying listed with a 50% discount, so I added them to my cart instead of the 30% off variant.

Tried some URL manipulation and the only other style of their goggles it worked with were the Black Magic Mirror Silver which are primarily suited to outdoor swimming

If you want a different style like Clear Magic or Blue Magic then you can append -bf at the end of the URL and it makes them 30% off, premade links provided below.

Description of the Lens Colours

• CLEAR MAGIC - This is our clearest goggle, hence the name. Perfect if you don't want any tint on your goggles and mainly swim in low-light conditions or indoor.
• BLUE MAGIC - Almost a clear view, only tinted with a light blue colour, enhancing the water color. These goggles will give you one of the clearest and undisturbed vision of all our available goggles. Truly amazing for indoor or low light swimming.
• BLUE MAGIC MIRROR GOLD - Blue lens gives a very bright and clear view while the gold mirror protects against excess light from sun/lamps.
• BLUE MAGIC MIRROR SILVER - Almost identical to the one above except that the silver mirror reflects more light and will be a bit darker.
• SMOKE MAGIC - Imagine wearing sunglasses. Amazing for sunny days or a super bright pool, but can definitely be more versatile if you do not mind a slightly darker view.
• BLACK MAGIC MIRROR SILVER - our darkest version. They are meant to be for outdoor (sunny) swimming unless you have an extremely well lit indoor pool or if you like to swim in the dark.
