I have been asked about re-making a site for a buddy that sells stuff online. Currently he is still using a site that was created 6 years ago and is very old. He runs a online farm store and has drop points where he makes deliveries.

Here are some of his most important requirements:
1. Price per pound (Very Important)
2. Group orders by drop point (pre-defined)
3. Payment on delivery

His less important requests (he said he is fine if I can't come up with a solution to these problems):
1. Print out a sheet that show all the orders for a particular drop point to make putting them together faster
2. Integration with ShopKeep

I have looked at a couple of the options in the add-on store but I can't quite tell which ones have the majority of the features I am looking for. I really like how Vivid's Store add-on looks and works.

Any advice that could point me in the right direction would be much appreciated! Thanks!
