Product mix pricing strategies involve setting prices for multiple related products to maximize overall profits. Key strategies include:
1) Product line pricing which sets price steps between similar products like "good-better-best".
2) Optional product pricing where high margins are set for optional accessories to generate profits.
3) Captive product pricing which recovers costs through high margins on supplies that must be used with the main product.
4) Two-part pricing uses a fixed fee plus variable usage rates for services like cellular plans or amusement parks.
Pricing by-products and product bundles also aims to earn extra profits or clear excess inventory.
