As everyone's said, site and idea look great!

suggestion - I'm not sure if you have this as a feature (I'd suspect you do) -- but allowing employees to vote on their perks would be great. Like if when company HR managers (or who ever sets team budgets) set the budget, they could go to your site, input that data, and know how many "points" (essentially dollars) worth of perks they can afford. Then employees could log on, and vote for which perks they like the most, and that's how the company could decide their perks plans
