Thrift stores can be great for budget diaper shopping.
I’ve gotten, for averaging about six bucks a pack, and just in the last month: two different kinds of the McKesson diapers (one didn’t fit despite the stated waistline on the package being in my range), some elastic diapers that don’t suck, for once… some of the plastic backed generic blue diapers that I love so much, even though they objectively suck… some of the Depends Protection, which are plastic-backed, triple tab, with elastic sections in the front and back waistbands… and like one other thing I don’t remember right now. Oh yeah, some bigger blue-purple paper-backed diapers that I really like for wetting.
I don’t do AB stuff, I just like wearing diapers, wetting them sometimes, vibrating myself in them, that kind of thing. This is fortunate because I’ve only seen ABDL diapers at a thrift store once, and I had a relative with me so I couldn’t buy any. I’m curious if they’re any good, but I don’t necessarily want the crazy patterns and cutesy stuff.
What I will say is, for a beginner, get the paper-backed, not the plastic-backed. As someone else kinda mentioned in this thread, once you place the tabs on a plastic diaper (which usually has to be completely dry on the outside for the tabs to stick, so good luck if you’re getting out the shower) you can’t really move them without destroying most of their adhesive. At least not on the three brands I’ve had.
Also avoid the elastic ones. Idk why they’ve taken off in popularity but the only good thing about them is that they fit more sizes—equally poorly! The sides are more narrow, which does not help their fluid retention, and they tend to lose their stretch and fall off if you wear them overnight and toss and turn.
If price is not an issue and you live in the US, I’d say go to CVS and get the regular “adult briefs,” in the bigger pack, paying attention to the waistline. If you’re close to the bigger end of the stated range, like for instance, if it says 25-30” and you wear a 28” pair of jeans, go up another size.
If you want extra padding get the “male incontinence pads” and use them as boosters inside the diaper. If you want crinkle, there’s “belted shields” (think of old sanitary napkin belts) that are kind of useless as far as actual incontinence, but they sure do crinkle and they sure are fun to wear under your clothes in public.
