Oops - its supposed to be delivered on Monday and realized I got the 12x18 granite plate. The 18x24 doesn't qualify for free shipping, but the 12x18 does with the code: PFSSEP - Free UPS Ground Shipping on your $25 order.
I got the code from another thread on NCWW - THX!!!!
You can probably get two of the smaller plates w/free shipping cheaper. I apologize for the mixup.
