Whimzees are not anywhere near being "expensive".Sure the larger ones cost more,but the small hamster sized ones are really inexpensive.The hedgehogs and alligators do cost more,but they last longer,so it isn't like you're paying more just for something that looks nicer.
Purchased in bulk,Whimzees are also even more affordable.This is especially true of discount pet supply websites(Chewy in the US,for example).
For US hamster owners wishing to use Chewy,the 24 count alligator small chews are extremely cheap(less than a dollar per chew):

Or the XS 48 count toothbrushes:

Meanwhile a bulk pack of teenie Greenies(way lower quality and definitely not worth buying to begin with)costs far more.Whimzees are by no means expensive if you know the right way to buy them,but of course when you buy them individually or at ridiculously high costs you're going to spend more but are also getting ripped off in a way!
Considering Whimzees are also good for dogs(unlike Greenies which are known to cause serious digestive upset in dogs,and the ones with grain have wheat which is absolutely terrible for dogs and should never be fed to dogs under any circumstances)they are much more useful.Greenies also contain unspecified fruit dyes,which instantly makes it unsafe for hamsters as the fruit could easily be a toxic variety.They have added minerals and vitamins as well,which can result in an imbalance(Whimzees do not,or it would be one only and in minimal amounts)and this is a serious concern since there is no way to regulate how much is ingested at once with chews like this especially since a lot of minerals and vitamins can be toxic in inappropriate levels
