Right, been in touch with DARTS in Chester who suppply clothing and embroidery services. They will do us Text printing on Polo shirts for free if we order 25 or more as it is for Charity.
He has given me a max cost per unit, but has said he is likely able to use surplus stock at the time of ordering to get us some or all at a cheaper price, rather than just pure catalogue ordering at the quoted price. This will mean any additional profits I make just add to the amount donated to Macmillan, through Whisper's just giving page with gift aid.
The easiest way for me to work it is to start a thread in the for sale section so it can't be posted all over where i will outline my costs, the prices, sizes and how to make pre payment and size orders prior to a date mid March when I will order them.
