To check availability of your size, please select band and cup size first, then you will see which color is available on the color menu.

The main difference between US430 and US4832 bras are the US4830 bras have thin foam padding while US 4832 bras have no foam and are just lined cups.
The flexible fitting size fits different band and cup combinations that are under the size menu. For instance M 34C/D 36B/C fits 34C 34D 36B 36C and so on. The first picture under the pink US4830 bra is from stock photos that shows how the bra looks on the person and size chart. Same purpose is for the last picture of black US4832 bra. These bras are mostly nylon with spandex and hand wash only.

No matter how many bras you buy, you pay fixed shipping for the first bra, even from different bra listings. The best way to get shipping discount automatically is to add items in your cart and check them out together.

Most bras were discontinued. I bought them at clearance so minor shelf wear might exist. I do my best to inspect them before shipping. You could see a needle hole after a security tag was removed. 
This note is only for items with volume pricing. Please note that you get volume pricing if you add items in a listing to a cart and check them out together. Ebay will give you volume pricing discount automatically. The discount is meant to save time. If you buy multiple items from the same listing but check them out more than once, ebay will not give you the intended volume pricing discount. And I am sorry that no manual adjustment will be given as it requires a bit of time. Thank you very much in advance for reading this and for your understanding. 

Regarding Volume pricing, it applies to different variations in case you are not sure about this. That means if you buy different colors and sizes from the same listing, you will still get volume pricing automatically at checkout from ebay. 

Also, if you buy items from different listing, I will manually give shipping discount based on your order. It's a win-win situation. An example is that if you buy a pair of shoes and a bra or shorts, then it's very likely that you will get the light item shipped for free if the weight added to your order does not increase shipping cost.
