Shipping For Multi-Item Packages?

[PKfanSteph]

Right now I have the shipping set up to charge $3.50 for one item and $1 for each additional item. However, I want to group several items together in a package, but it would cost me more to ship. For example, if I sell 4 different DVDs for $20 each individually, that would be $80 + ($3.50 + $1 + $1 + $1) = $86.50. But I want to give my customers a discount for buying the DVDs as a set, say all four DVDs for $70. If I set that up as a single product, I will end up only charging $3.50 for shipping, in which case, I lose money.

 

How else can I do this? How would I tell the software that there's really more than one item there and I need to charge more in this one instance?

 

Thanks,
