when i add it to kart it says 20$ not the 14.99

should have a savings under the reg price.

Couldn't ask this in one of the various Amazon threads that already exist?

Just go on through checkout. The discount should appear on the final page before you click the place order button.

thanks i seen it says 5$ off now man i am spending way to much money but cant pass up these deals

It will deduct the lightning deal amount when you approve the final purchase... it will show up on the last button you click to finalize your transaction.
