3m prices go up regularly, they don't need a reason they are 3m
we can buy direct from 3m and it's crazy the way their pricing goes
another thing that kills me about them is if you are a distributor of their products you can only be approved to sell certain items. They have different departments and if your sell something from one department that doesn't mean that you can sell something from another department (i used to buy vinyl from one distributer and then tried to buy some adhesive from them and they weren't allowed to sell that product) wouldn't you make more money if you just let your distributors sell all your products?
