Whilst group buying sites like Groupon and KGBDeals are not solely about beauty, I tend to only really use them for such purposes. I’ve used both these sites quite a lot over the past couple of years and I’d say my experiences are mostly positive, although it’s fair to say I’ve read a few horror stories too.
Groupon has been around the longest and operates by area. You normally get 3-4 deals ranging from things like a pamper session to a day’s car hire. You usually have 24 hours to purchase the deal – from midnight to 23.59 – and then you receive a voucher for the deal.
KGBDeals operates slightly differently as they have several deals running at the same time for longer periods of time (usually around 5-7 days). Once you purchase the deal, you receive your voucher straight away. Deals get updated nightly at around midnight too.
