MI Supplies Discount Codes July 2025

Amid the paradoxes of modern adulting - worrying about the biomechanics of your arches while barely making peace with your inbox - the arrival of well-constructed workwear can feel perversely soothing. Function meets necessity, with the occasional nod to aesthetics, raising the very modest bar set by the average polo shirt or steel-toe boot. Still, even practical purchases benefit from rationale, and believe it or not, the world of work trousers and safety footwear is not immune to the enticing pull of a discount code. Welcome to MI Supplies - one of the better places to buy a three-pack of flame-retardant hi-vis shirts and still feel vaguely in control of your life.

Carhartt for the Disillusioned Adult

It’s hard to oversell Carhartt - and to be clear, we’re not going to try. The American workwear brand has been around since 1889, impressively surviving world wars, fashion cycles, and an uncomfortable amount of TikTok-based revival. The Carhartt Workwear line, distinct from its streetwear cousin Carhartt WIP, deals in steel toes and reinforced stitching instead of stylised nostalgia. At MI Supplies, they’ve amassed what could be generously described as the UK’s most comprehensive Carhartt stockpile - fine news if you’ve ever tried tracking down a reliable size 11 waterproof safety boot in winter.

The current top pick: the Carhartt F702901 Hamilton S3 Waterproof Wedge Boot in timeless "muddy tan." Priced at £115.64 (VAT free), it’s perhaps not an impulse buy, but certainly cheaper than a podiatrist. It’s thoughtfully wide-fit - finally acknowledging that most people's feet are not shaped like an A4 envelope. Waterproofing is a plus, the design is solid, and the material doesn’t squeak like discount leather. You may not cry tears of joy upon unboxing, but your heels will likely stop doing that thing where they protest at the top of each staircase.

There’s also the Detroit 8" S3 Waterproof High Boot for £122.91 (VAT free), which is just slightly tougher-looking. High-shafted, reinforced, and arguably excessive unless your commute includes trench warfare. Still, it’s built to last and doesn’t scream "health & safety cosplay."

Coupon Codes, But Make Them Useful

MI Supplies is offering £10 off Carhartt when you spend £140 - code: 10OFFCARHARTT. Not revolutionary, but in what other universe are you being encouraged to buy exactly one-and-a-third boots?

Shipping is dependable, with most in-stock UK orders shipped within 1–3 days for around £3.95. Returns are where MI quietly outplays the rest of the field: 365 days, no quibbles, no accusatory email threads. They seem to understand that buyer’s remorse doesn’t always clock in within 14 days, especially when it’s buried under receipts and life admin.

Mascot: Solid Mid-Tier, Plain On Purpose

The Mascot F1002 S3S Safety Boot at £89 (down from £112.95) is neither flashy nor particularly chatty. It’s the Lidl of safety boots - competent, unpretentious, and weirdly comforting in its modesty. It doesn’t pretend to be a hiking boot or a lifestyle choice. It’s work gear, plain and simple, and for many that's exactly right.

The fit is standard, which is great if you're standard. It works, it holds up, and it has that all-important slip resistance so you can walk across spilling coolant like it’s just another Tuesday.

Bulk Orders & The Quiet Joy of Uniformity

For those kitting out their team or crew - or staging a very niche flash mob - MI’s bulk order service is surprisingly lean. Discounts kick in at five garments, with more generous pricing if your order volume enters small-platoon territory. Embroidery services are available too, ideal if you like your logos professionally stitched and not just ironed-on tragedies. No setup fees either, which is the embroidery equivalent of having a friend with a van.

A Word on Prices and Reality

This is workwear, not wireless earbuds. You’re probably not going to read reviews aloud to your pets or unbox your high-vis waterproofs on YouTube. That said, the deals at MI Supplies are decent, the stock refreshes regularly, and the 365-day return policy gives space for quiet indecision. They’ve put effort into curating serious brands - Carhartt, Mascot, Dickies, Snickers - and less so into glitzy marketing jargon or "drops." Which is refreshing, frankly.

Quality and realism rarely intersect at a retail checkout. But when you find yourself adding waterproof gloves, steel-capped sneakers, and a budget first-aid kit to your basket during lunch, it helps to know someone out there took the fittings seriously - and added a coupon code for good measure.
