I'm on a budget and the prices for some Tena diapers on amazon seems to be too good to be true. There are cases of the Tena Classic for $36 for 100 diapers. Can anyone tell me if these diapers are ok? There are other cheap Tena's on Amazon such as the Ultra, but I prefer individual tabs and not those velcro things I think the Ultra has. Really any advice/reviews on the cheaper Tena's on Amazon would be really helpful to me. Also, some reviews said they run small? I have a 32 inch waist, which should easily fit a medium, but will they be too snug?
