Heads up, awardtrail readers! TopCashback is running a flash promotion where you can score an extra $2.50 cashback when you spend $15 or more through their shopping portal. The catch? You need to activate the offer *today* via the provided link. This is a targeted offer for select members, so make sure you check if you're eligible. Why is this useful for savvy travelers like us? Well, shopping portals are a fantastic way to earn extra rewards on purchases you'd make anyway. Even better, TopCashback sells gift cards, which means you can essentially buy a gift card to your favorite store and get cashback both from your credit card and from TopCashback! Just make sure you read the fine print, as some merchants are excluded from the promotion (Booking.com and Hotels.com for instance). A quick word of caution: In the past, some users who purchased gift cards through TopCashback to meet the spending threshold have had to manually contact customer service to get their bonus cashback applied. It sounds like this was a one-time issue, but keep an eye on your account just in case!
