If you shop on Amazon or any other online marketplace and you're not using these two free browser extensions, there is a very strong possibility you're paying too much for the things you buy.
Wikibuy, while useful for everyone, is targeted at Amazon Prime members. It scours the web for coupons, promo codes and better prices for your chosen product from other sites, as well as watching prices for you so you know the moment they change. Now, those other sites will likely have longer shipping speeds, but let's face it: very little of what we buy on Amazon is an immediate need. We go to our local stores for those things whenever possible. So, odds are you can probably stand to wait the extra time to receive whatever product you happen to be buying. Wikibuy also has a reward program, which lets you earn based on what you spend and what you save, plus bonuses for referrals. Speaking of referrals, here is mine so you can get started saving and earning rewards today.
Like Wikibuy, Honey is another extension that searches for online discounts, coupons and promo codes and tracks product prices for you. You can still earn rewards and get referral bonuses, too. Honey, however, seems to have a wider scope than Wikibuy and is not limited to online markets. Using both provides you with the best chance of saving and earning simultaneously, so go check out Honey and rack up that sweet Honey Gold while you save more and spend less.
I'll be on the lookout for more opportunities like these to save and earn for the things you already do.
