here is a nifty little app that i use to make some extra money. i was lucky enough to score a gig through them for whole foods that lasted for several months and involved me simply attaching coupons to certain products on the shelves. each job only took me 10 minutes and paid $12. i made nearly $200 for the duration of the project and it was super easy. payment was through paypal.
here is the link: https://survey.com
they also often have walmart merchandising jobs where you actually go in and re-merchandise or change out signage for certain products. for some reason it is never any walmarts near me so i haven't tried one of those jobs yet.
it is actually two different apps. one app, survey.com, is available for both apple and android, and is more survey based. screeners for bigger projects will show up here as well. if selected, you then download their second app, survey-merchandiser. please note, DO NOT download the survey-merchandiser app unless you have been approved to do so. from their site:
"Only download this application if you have explicitly been instructed.
This application is for approved users only."
good luck and and may the surveys be with you :)
