I need a modification of my shopping cart (Jigoshop) or another one if you think its better. I need customers to be able to look at my products and be able to follow through with their buy of the product by attaching their credit cards and clicking ok, but not actually charging the customers untill a minimum amount of people/products have been bought. So say 15 people have bought 15 products, i dont want anyone to be charged/bought untill 100 products have been bought. I would also need the number that is currently needed to be availible clearly for each product.
