Not sure I understand the hesitation. I believe they pay a higher wage than Walmart...
We have an Aldi down the street. It's a small store because they tend to carry only one of everything. One ketchup but you can tell it's Heinz 57 in their own private label bottle. Same with the French's Mustard and on through all their products. They tend to be a private label version of whatever the top brand is Ina big supermarket. They do take debit cards. And the beauty if the .25 cent carriage is that you're not paying higher prices to put someone outside to collect carriages in huge parking lot. Either people return it cuz they want their quarter back or they leave it and someone else gets a free quarter. Win win.
We don't use it as our primary grocery, they don't have everything, but they are alright from time to time.
I'm probably one of very few campers who hates walmart, I don't set foot in there, I can't stand the atmosphere, the blue color, the people, and all the endless aisles of stuff. It's very difficult to be in and out of a walmart in 5-10min. An ALdi you can be in and out quickly. It's no larger than a gas station convenience store most of the time, but with ride useful products and less junk food, lottery tickets, cigarettes and dirty magazines and keno. Haha.
So I'd say give it a shot if you haven't yet and see what you think. It's not for everyone. The usually have a section towards the back with seasonal non-grocery items and this is where you can find some interesting deals on garden, camping, sporting goods.
