No immediate plans to accept other payment methods.  You can use credit card during Paypal payment if desired.  The marketplace is not a focus of ours on the site at this time so we are spending development efforts in other locations.

You can do this now with search results or collections.

In search:

Choose "Filter by Console" or "Filter by Set" drop down (exact wording depends on the results).

And choose the set you want.

In collection:

Filter by the category first (pokemon, video games, etc)

Then choose "Filter by Set" from that list.

Thanks for the feedback.  99% of the users on the site don't pay anything to use the site.  All the basic tools, like prices, collection tracking, etc are free.  Only premium tools cost extra.

This is already a feature on the site.

Good feedback.  Thanks for letting us know and playing the game.  Besides getting low scores because of Loose condition, was it fun?

Just FYI.  This game is live on the site now.

I think it turned out really nice.  People say they enjoy it.  Thanks for sharing your idea and discussing this with me.
