Ok. I'll start. Since it seems that the 870 each to buy a haversack, a wand of lesser vigor and a pair of scrolls of restoration is too much, I will suggest to ditch the haversack.
While I think it is quite important, I guess the other items are that much more important. This means a total cost of 2,350 (or a share of 470 gp each)
This is what I will mark on my sheet.
