Whenever I shop for something online I always look for a discount, and it solely because of how easy it is to find promo codes, coupon codes, etc.  While I will usually just search for the term and promo code, Wikipedia highlights a ton of other synonyms that should be looked into,

Online retailers often refer to coupons as “coupon codes,” “promotional codes,” “promotion codes,” “discount codes,” “key codes,” “promo codes,” “surplus codes,” “portable codes,” “shopping codes,” “voucher codes,” “reward codes” “discount vouchers” or “source codes.” Internet coupons typically provide for reduced cost or free shipping, a specific dollar or percentage discount, or some other offer to encourage consumers to purchase specific products or to purchase from specific retailers.

I had never heard of some of those terms including discount vouchers and source codes.

 

Do you normally search for promotional codes?
