Need Shipping Help!

What's the cheapest way I can send individuals of the following items:

- SNES Games
- Gameboy Games (Original)

I tried looking for some sort of flat rate envelope but no luck. Help me and give me full costs of shipping (after buying postage and all)<3

Thanks.

 

Depends, are you planning on it being flew in or delievered by a road transport.

 

Oh yeah my bad, road transport.

 

USPS offers flat rate boxes all throughout the US.

 

USPS is the best option. It's like $4 to send them in an envelope. That's not a bad price, if it's through eBay or something just put the shipping fees on the buyer.
