I searched this and did not see it, so sorry if it was a repost.
Shipping is high, $7 but still for $12 total it is not too bad.
I should mention that you get free shipping if you add any Piperlime item to your shopping cart. Use code PLFREE at checkout. (expires 10/2)
The only coupon I found was ONSAVE20 that is good until 9/30. Save 20% + Free Shipping if you spend $75.
