Hey guys, been lifting for about 7 months now and I have gotten all types of stuff from airplane luggage, to food, utensils, curtains, Xbox controllers, routers and more. I'm just here to tell you some of the methods I use to lift in case it might help you. Also note that I go to a 24 hr Walmart always around 12-1am.
#1: Self-Checkout is your best friend. I typically will just grab a basket, fill it up and then pay for one item, bag it, and put the other items in the same bag. It also helps to take advantage whenever the self checkout clerk goes to help someone.(There are always problems to distract workers at self checkout). Also remember to never EVER place items on the scale or a worker will be notified. Once everything is bagged you can finish the transaction like a normal customer and just walk out undetected.
#2: Return Method(Requires Money): Broke a pair of earbuds and need new ones? Simple. Just go buy the best earbuds they got and place your old broken ones in the package and return. Need a better router? Easy! Buy a nighthawk and then place your old shit router back in the box and return. I find that this method is extremely safe and pretty much fool proof and will help you replace your broken garbage with fresh new shiny products. Just remember that some items that are expensive (typically spiderwrapped) require a serial number check so remember to swap stickers from item to item.
Other methods I sometimes employ are just the quick slip in the pocket method. Or if you're taking an object that has storage space, always put it to use. Try filing a back pack full of merchandise and then just pay for the bag. It's safe but extremely valuable. And who cares if you just paid 30$ for a bag as a method of transporting stolen goods when you can always return it with receipt for the full refund.
Good luck out there y'all!
