Why? Because for a single traveler you're more than twice the cost! I can do round trip for $45 on a bus, so I wish you had a separate, cheaper price category for single passengers (like $70 or $80 round-trip) instead of having them in the 1-3 passenger category for $110 (for 2 or 3 passengers the cost is almost the same as the Bus, so your service makes alot of sense for them!).
