You may have already seen the premade filters on the Oddsmatching Software, which are primarily used for the Welcome Offers.
You may find that some offers are not showing, but there is a simple way around this.

If you cannot find a selection for your offer, you can use the manual filters at the top of the page

Simply, select your Sport, Bookmaker, Exchange and check the minimum odds for the offer to add in the correct range.
Just like the premade filters, this will bring up the results that fit within your given range.
