When You Simply Can’t Compete
The Canadian dealer cost price on Exodus: Gods and Kings is $28.26 at David C. Cook, and when you do the conversion at Send the Light (STL) it’s more or less the same. Meanwhile, Walmart Canada has it for $19.99, 29.3% less. You would do better to buy them there if you wanted to resell them. But the best thing would be to either (a) tell your customer to wait, the price will be coming down soon; or (b) refer your customer to Walmart hoping they appreciate the honesty and you doing them a favor.
