classifieds 2.4 latest release
Currently bid steps seems to be hardcodes, but are IMO too big (10USD) and bid steps in 0.5 not possible at all.
This should IMO made as an option in the admin menu, so every administrator can use for his own needs the right setting.
IMO the most usable setting is to allow any kind of higher bids, even if it is only in cents of .05 or .01.
a) small items are often not worth the price, if the next step is 10 USD
b) Only with small steps like 0.05 or .01 cent, you do ensure that bidders are not afraid to be forced to pay more than they actually wanted to. And this is mandatory to attract as many users as possible for an auction
Even if the price is already at 500USD, many bidders only want to go higher to i.e. 500.23 USD. You see this very often on ebay auctions...
