        Gprice=0
        Sprice=0
        Cprice=0
        Amount=1

    proc/price()
        if(usr.C < 0)
            usr.S-=1
            usr.C+=100
        if(usr.S < 0)
            usr.G-=1
            usr.S+=100
        if(usr.G ==0 )
            view() <<"you need more gold!"


obj/weapon/

sword
    desc = "+5 power"
    icon = 'sword.dmi'
    Gprice=0
    Sprice=5
    Cprice=3
    var

        Aug=5


    verb
        get()
            set src in oview()
            loc = usr
            suffix=desc
        drop()
            set src in usr
            loc = usr.loc       

        equip()
            if(usr.EquippedWeapon==0)
                src.name="sword"
                usr.EquippedWeapon=1
                usr.pow +=src.Aug
                usr.Rage()
            view()<< "equipped [src.name]"

        unequip()
            if(usr.EquippedWeapon==1)
                src.name="sword"
                usr.EquippedWeapon=0
                usr.pow -=src.Aug
            view()<<"unequipped [src.name]"

ok so this is the shop code(not finished till stack works)
mob/shopkeeper

    weapon_shop
        icon = 'shop.dmi'
        var/list/Inventory=list()
        old_town_man
            Inventory=list(new/obj/weapon/sword,new/obj/armor/)
        verb/Shop()
            set src in oview(1)
            while(1)  //Create an infinite loop
                switch(alert("What would you like to do?","Shopping","Buy","Sell","Cancel"))
                    if("Cancel") return
                    if("Buy")
                        var/obj/O=input("What item would you like to buy?","Buying")as null|anything in Inventory
                        if(!O) continue  //If O is null, restart the loop
                        if(istype(O,/obj/weapon))  //If O is of the /obj/weapon type
                            var/Quantity=input("How many would you like to buy?","Buying [O.name],[O.Gprice]G,[O.Sprice]S,[O.Cprice]")as null|num
                            Quantity=round(abs(Quantity))  //Make sure Quantity is positive whole number.
                            if(!Quantity||usr.G<O.Gprice*Quantity) continue  //If Quantity is null OR the player does not have enough money, restart the loop
                            O.price()
                            usr.G-=O.Gprice*Quantity
                            O.price()
                            usr.S-=O.Sprice*Quantity
                            O.price()
                            usr.C-=O.Cprice*Quantity
                            O.price()
                            var/obj/N=locate(O.type) in usr.contents  //Try to find an object that has the same type as O in the player's contents.
                            if(N)  //If it exists...
                                N.Amount+=Quantity  //Add the amount to the existing item.
                            else  //If it doesn't...
                                N=new O.type  //Create a new obj with the type of B.
                                N.Amount=Quantity  //Add the amount to the new item.
                                usr.contents+=N  //Add it to the player's contents.
                        usr<<"Old Man: Thank you!"
                        return  //End the loop.


and in my stats i have the following inventory: statpanel("inventory",usr.contents)...so if you can help thank you and if you need more just ask ill add but this is what seemed significant

It doesn't look like you've done anything stack related so far? Are you looking for someone to help you create a stacking system, or provide advice on how to make one?

well help would be great but ill go for advice. im just not sure how to go about it from here. and the shop code was modified from a forum post i found so i thought that the last part 
                 var/obj/N=locate(O.type) in usr.contents  //Try to find an object that has the same type as O in the player's contents.
                            if(N)  //If it exists...
                                N.Amount+=Quantity  //Add the amount to the existing item.
                            else  //If it doesn't...
                                N=new O.type  //Create a new obj with the type of O.
                                N.Amount=Quantity  //Add the amount to the new item.
                                usr.contents+=N  //Add it to the player's contents.
                        usr<<"Old Man: Thank you!"
                        return  //End the loop.

was for that very purpose but i guesse i still have a lot to learn :S
