Shipping Cheaper in the US- Flat Rate Regional

Everyone should save money on shipping, and it may be helpful for your sales and purchases in the future.
If you don't already know about regional flat rate, I'm going to tell you all about it. 

If you can get ahold of a regional flat rate box A, you can fit items as large as skirts or lighter-material jsks into them for cheap.  B is larger, and can fit OPs. They cost $3-$7 less than standard flat rate, depending upon the destination. You will also be saving money on packaging because the boxes are free, and it frequently ends up being cheaper than standard post. Because it is still priority mail, your package will arrive quickly– typically in 3 days.

They don't always carry regional boxes in the post offices, but you can order them for free on the USPS.com website:

Go here for flat rate regional boxes if your local post office doesn't have them.

If you purchase shipping online, you can save up to another dollar, but you cannot purchase the shipping label on paypal. You must buy it on USPS.com, or in the post office, and then update the tracking info onto paypal or wherever it is you want your buyer's tracking number to be seen.

If you purchase shipping from the USPS website, do not select flat rate shipping or it won't show up! Select "package" on the first screen and then enter any weight up to 15 lbs (you don't need to know the real weight since it will be flat rate, assuming the dress isn't made of lead)...

and then select  "Priority Mail®,"  and it will show up: 

Savings. Juicy, delicious, savings.

Hopefully some of you can start saving a bit of money with this method of shipping!
