Blood bags

The customer for the blood bags (single and triple) call me yesterday
He need samples for : Blood Bag Single, CPDA-1 Tranfusion (Giving) Set OP.
He needed 7-10 pcs for each one How much it takes you to prepare it? and when you can send it?
Regard the tribe blood bags, I asked him about if he need samples, he replies that our offer is not the lower so he did not ask for samples
But if we can give him a discount, maybe he will restudy the situation and may change his decision.
What do you
