I recently purchased a SpotHero voucher for $24 for parking from 8:30 AM to 11:00 PM. When I arrived at the garage at 8:12 AM, I notice that they had "early bird parking" for $19. When I called SpotHero support, they told me that I should pay for parking on my own, send them a copy of the receipt, and they'd credit my account for the $24 I paid them. I did so, and the credit quickly appeared on my credit card. Perfect support! Thanks SpotHero.
