Soda Stream, the frm referenced in question 15, sells sof drink producing equipment to consumers. But the

equipment itself is useless without the favorings, carbonator, botles, and botle tops needed to make the sof

drinks. SodaStream conveniently sells all of the other items needed to use the equipment. So, SodaStream sells the

equipment and then the ingredients etc needed. Soda Streamms business model is an example of:

a. frst degree price discrimination.

b. a tie-in sale or a two-part tarif.

c. versioning.

d. third degree price discrimination.

e. block pricing.
