In my experience, the reseller agents don't even offer better prices these days.

So I'll typically use a service like Google Flights to find a flight, pick an itinerary, but then go to the airline's web page to book the flight directly.

Same for hotels. Find a hotel on Expedia, then book with the hotel directly.

I've seen too many horror stories of people booking through a reseller, and if something goes wrong, the reseller tells you to talk to the hotel/airline while the hotel/airline tells you to talk to the reseller.
