Shipping & handling: how soon do you really need it?

Ordered oversized, glossy postcards from VistaPrint.com—incidentally announcing my new Blogs. The two pricing choices I considered were $13 for 14 days and $5.95 for 21 days. Thing is, last time I ordered postcards I marked my calendar with the estimated delivery date, and the postcards came in 9 days earlier than anticipated. So, I chose to save 7 bucks by selecting “slow” versus “expedited” and will take my chances. Oh, yeah, upon entering the right code, the 50 postcards—valued at $20—were FREE, so I went ahead and paid 10 bucks for color printing on the back. Total $15.95 for 50 oversized color glossy marketing postcards. Not bad, unless anyone knows of a better deal out there.
