Nice idea but badly implemeted. One big reason:
Low combat levels (or CL) are following legacy most likely and will not need those weapons so you will have to buy better ones.
So some suggestions:
1.Your best CL range to market to is CL 50+ as they are done with legacy. So I recemmed getting survival packs made specifically for a specific type of profession so find an expertise calculator and see what it supports (for example a BH pack would have a carbine and a rifle).
2.HoT (heal over time) stims are what domestics make (if that is what you are) so they are only good for cloakers so it is best to jsut put those in spy packs and/or sell them seperatly.
3.Put in food/drink that increases harvesting.
4.Put in food/drink that gives a good buff.
5.If the MSE isn't a droid to increase harvesting or a bomb droid or a combat droid best remove of it. Put in a harvesting droid and a combat droid (but if its for BH's put in a bomb droid).
Ok, I know you said you are marketing to low levels but if market to higher CL's were they actually have more thank 40K credits you can probably make better money.
