[quote name='lothodon']There is a lot of misinformation here.
Priority mail is great IF you need a box and don't already have one. $4.95 is the cheapest Priority Mail cost and delivery confirmation is an additional $.80.
First class is cheaper, however you need to provide the packaging. Delivery confirmation is still an additional 80 cents.
Media mail is cheapest yet (and slowest) and similar to first class in the fact that you need to provide the packaging and delivery confirmation costs.
Goozex shipping labels round up, always, and are more expensive than going to the post office. You pay for convenience and Goozex makes the extra in profit (if i recall). It does save you a trip to the post office though.
Something to remember, if your "buyer" on Goozex get's hit with an underpaid shipment, your going to get negative feedback right quick, no matter what online method you choose to ship with.[/QUOTE]
All correct, but I stand by my statement that PayPal shipping is your cheapest option and also extremely convenient.
As others have said, if you're planning on sending a lot of stuff (and if you're on GOOZEX, you probably are), it's worth your while to pick up a postal or kitchen scale (I recommend the latter, especially if you cook at all since it can do double duty). It'll give you peace of mind that you're not underestimating the shipping weight, and can save you a few cents on each shipment by being accurate to the oz.
