How practical is presta? USPS Shipping charges on Small stuff but different quantities.

[Billy]

How practical is presta? I have a website that we want to use the USPS for all shipments. This is an arcade related website that sells old school electronics to repair 80's style arcade games. So as you can imagine we need some ideas on the best way to pull off USPS shipping.

We don't want to run customers off because of shipping prices being to high. I have read a lot of the different threads on the usps here on presta. I have artjunky.org's modules but have not yet installed them. I have also read thru the wonderful posts by debra about USPS Priority mail shipping rates. http://www.prestashop.com/forums/viewthread/14003/

I am almost done with the design phase of this website. So it's time to start asking the pros here about setting up quantities vs the shipping amount and so fourth. We love to ship http://www.usps.com/shipping/prioritymail.htm that should be with out saying but how can we get the electronic parts to fit the priority boxes. What do we do with customers that only want one eprom? They are about as big as a mini bic lighter (meaning really small).

Do you set up quantities of stuff like

1 chip
5 chips
10 chips

and then set shipping accordingly to each?

Do you have any other threads to recommend that I might read to gain some more knowledge? What is your take on setting up our products to ship and then setting the shipping up in presta.

How would you set it up is what I really want to know???

Thanks in Advance for your Wisdom!
