Vegas.com takes $50 off bookings of $100 or more via coupon code "VISACHECKOUT" when you pay using Visa Checkout. That's the largest dollar-off coupon we've seen from Vegas.com. The discount can be applied toward hotels, vacations, show tickets, tours, and attractions. Several conditions apply. Deal ends March 31.
Of note, you can either apply the code during checkout or on the front page when you select "Heard about us on radio or TV?" in the top right corner.
