Sephora $100 Gift Card Instant Win Giveaway -5,210 Winners! Daily Entry. Ends 8/23/20. People have been playing this each day and winning multiple times. One tip they are doing is they are entering right when at the time when their store is supposed to open. When you enter you pick your local store, so look up the time it opens. Then enter right at that time. If you are the first to enter at the time you have a great chance of winning this. I've seen people who have win 4 and 5 times already by doing that. IF YOU MISS THAT TIME then try entering at any time of the day anyways, but it seems the best chance is at opening time. GOOD LUCK!!
