I use www.shutterfly.com for services that I can not do at home. They offer poster sizes 16x18 and 20x30.
16 x 24 = $25.00
20 x 30 = $30.00
24 x 36 = $50.00
The above prices do not include shipping. Shipping is an extra $10.50 per order, so the more per order the lower the shipping (i.e. 1 20x30 would be $40.50, 2 20x30 would be $75.00, ect. BUT if you order 1 now and 1 later it would be $81.00)
When these services are used, I upload the desired photos and have the order shipped to me. I will then get them to you, payment on delivery.
NOTE: Once I upload the photos I do not have control as to the final quality of what you have ordered.
16 x 18 = $30.00
20 x 30 = $35.00
Bulk Calendars = $30.00 each
