For now, Christmas Delivery is Guaranteed – see this link for shipping cutoff information and read the article below
For most of December, Priority mail is our most popular option because it is so fast and affordable. A typical 2-pound order arrives in 2-3 days and costs $4.95 within the US. We ship most orders same-day because everything you see in the store is in-stock and ready to go. That’s our In-Stock Policy!
According the USPS the cutoff date for Dec 24th delivery anywhere in the US is Dec 20 for priority mail. We can guarantee that orders placed by 4PM will be shipped same-day but we cannot guarantee the USPS’s own performance.
So, our recommendation is trusting priority mail for now, but soon we will strongly encourage use of Fedex 3-day Saver or 2nd Day Air for guaranteed Christmas delivery.
This is still a good time to shop for Christmas presents and not worry about getting your packages in time!
