KFC (via KFC App or Skip) - BOGO Hot Wings

There is an offer in the Skip app for BOGO on 5 or 10 pc Hot Wings from KFC. Skip prices, as expected, are more expensive than the 'regular' 10 for $10 promo directly from KFC, BUT if you have a coupon sitting in your account ($5 - $10 vouchers sitting in your account if you haven't ordered in a while (or have a 30% off code from the Blue Jays promo), it is cheaper and is a decent deal.

Alternatively, KFC also has BOGO on the 10pc wings only, so it's $17.29 for 20 (YMMV).

Comparing the 2 (I only had a 30% off Jays code), Skip was still cheaper ($17.xx including tax).
