If you are looking to buy cheap scrubs, you might want to check out this online store I know. Blueskyscrubs.com offers nursing uniforms and scrubs. They have a variety of uniforms to choose from and you may find the ones at your desired price.
I have checked this site before but I have never tried yet buying since I don't need nursing scrubs as for now. I did check for my friends who work in the medical field. I will still check the site in the future for I really like to work in the medical field. I might want to get a medical course someday. So if you are like me and looking, try visiting the site then. Hope you will find what you are looking for.
