You could instead get a discount on the products from a certain manufacturer for using them lots, similar to bulk buying. So, if you buy 1-5 parts you get a 10% reduction 6-12 = 20% off 13-50 = 30% off 50-100 = 35% off 100+ = 40% off These numbers may be to higher a discount but this could be balanced depending on difficulty? You could also include rep in this, if you have good rep, you get better discounts, 26% off instead of 20%? As to weather or not you include individual manufactures reps in this is up to squad, (that is, if they even plan on doing anything like this) This would add even more reason to get a better rep. Sam
