Research: Buying in Bulk

I have come to a decision after doing some research that i will be bulk-buying t-shirts, and printing on them myself, this is a far more cost effective method of producing the t-shirts.

Below is a picture of the price i was quoted for 20 t-shirts, at £57. i thought this was a very good price, and would work out a whole lot cheaper than buying t-shirts with my design on from a professional t-shirt maker, However, to be sure i will need to conduct some further research on the alternative methods available.
