Total rip off... They sale you the voucher but fail to back it up. I purchased 4 tickets through a vendor who decided to have blackout dates until the expired date of the voucher. I emailed Dealfind and included my call logs where I've been calling the company and screenprints of the website saying they arr closed due to weather conditions. Keep in mind Los Angeles has been in the mid 70' to the mid 80's so I see no bad weather condition for a short boat ride. Anyway, Dealfind said they are unable to offer a refund because its after the 7 days of purchase as if I knew months ago that the company was going to pull this and rob me of four roundtrio tickets.
DEALFIND will find the deal but don't expect them to back the deal or even care if you were able to enjoy your purchase.
Don't do business with them. Learn from my mistake.
