You can tell if it’s an affiliate link if you move your mouse over the link and look at the url.
(that’s a fake affiliate code btw).
Everything after the .html is the affiliate code (so in the above link, the ?p=ZZ2317254917312414AA is the affiliate code). The person posting their affiliate link gets paid if you purchase a product using their affiliate code link.
The reason why most forums ban affiliate links is because it makes people just keep posting nonsense links over and over just cluttering up the forum with useless crap.
If you see a link to a product, and it has the ?p=ZF9873498 code at the end, just right click on it, “copy shortcut”, then paste it in the address box of your browser, and remove everything after the .html before pressing enter voila, product page with no affiliate payout.
Now says $14.95 with the coupon? Price increased $1? When I try and buy more than one pair the coupon is worth LESS as well Was trying to order 3 pairs
