I sometimes remove my diecast from their card/blisters and store them in 48 car cases, which i purchased from Walmart. No longer in stock, i decided to contact the makers of the cases at planomolding.com. Although the cases themselves are reasonably priced, the shipping via UPS (and brokerage costs) will be too much. Here is the response from planomolding's customer support:
Pertaining to your inquiry regarding one of our JAMMER products, the 5315. Although not featured on our website it is still a current product and can be ordered directly through our credit card department. Through this service the 5315 would be priced at $4.00 per piece plus the cost of UPS shipping. We do not send our credit card orders out via the postal system.
The most economical way to ship this item would be in full cartons which would consist of 6 pieces. The UPS charges would be $19.10. This UPS cost does not include any additional duties, taxes, etc. that might incur.
To place an order contact our department at 1-800-226-9868 Monday through Friday between the hours of 7:30am and 4:00pm (Central Time).
Thank you for your continued interest in our products.
