How do I set up different prices for wholesale and retailer?
You can group your customers into different price families and then create price lists for those price families in sales - sales price list - green button - new sales price list. Open the advanced section and select the price family for which you set up the prices. Add your products and modify the sales price according to your needs.
If you then create a sales document for a customer within that price list, the correct price will be pulled into the sales lines.

Why is my price for the pack unit wrong, even if it shows correctly in the price list?
Please note that you will need to set up the prices for the units and not the pack unit. So, if you have a pack unit 1 pack = 20 units, you will need to register your price list like this:
0 - 20 = 20.00 (1 pack unit)
21 - 60 = 19.00 (2 to 3 pack units)
61 - 100 = 15.00 (4 to 5 pack units)
