Hi. I was hoping someone might be able to flick a switch in my head that allows me to understand the answer to a question i've been asking myself..
How do I keep costs consistent, for customers imparticular. My logic goes as far as, buying the same amount each time I replenish stock so that the amount I buy costs the same each time (no price breaks) and the delivery costs are split among stock evenly each time, but unfortunately its never that convenient and sometime you need to buy more of one thing and sometimes non of another.
Just as an example; say I bought 100 sheets of sub paper at £25 and £5 delivery, this would be 30p a sheet. But then I knew I needed 200 sheets for an order - £50 and £5 delivery, this would be 27p a sheet; Its a basic example and only involves 1 type of item but its just to help explain what I'm trying to figure out.
Hopefully this makes sense??
