In the rules it says to put your marker on the 50 gold mark on the camel track and put the camels in oasis and each camel gives you 50 gold off the auction bids. But what do the 70,100 and 150 mean then? How do you move the token or is it a missprint and you move it each time you buy a camel and that is the new amount you get off?
Initially, for each camel you have, you receive the 50 gold discount on bids (so with 3 camels, say, you're getting 3 x 50 = 150 bid discount). Through play of the "Better Breed" event card - and only in this way - you can move your discount one space to the right (so now, you're getting 3 x 70 = 210 bid discount). Additional "Better Breed" cards may move the discount per camel higher, up to the maximum.
