Why use Promo Magpie?
Every eSUN deal here comes from eSUN itself or its official affiliate program, never copied from another coupon site. When you shop through our links, eSUN may pay us a commission. It never changes your price. We give 50% of that commission to the charity, club or school you choose, at no extra cost to you.

Most come on 1kg spools, with bulk packs from 2kg up to 15kg, 250g sampler bundles and refill spools.

Are these eSUN codes verified?
Every eSUN code here comes from eSUN itself: its own daily feed through its official affiliate program, or its own website. Each offer shows when we last checked it.
Does Promo Magpie donate to charity?
Yes. When you buy from eSUN through our links, eSUN pays us a commission, and we give 50% of it to the charity or club you choose. We pay each cause its confirmed commission every quarter (Jan, Apr, Jul, Oct), once the store has confirmed the sale, usually 30 to 90 days after the order.
Does using Promo Magpie cost more?
No. You pay eSUN's normal price, less any discount. Our commission is paid by eSUN or its affiliate network, not by you.
