Contact the critterstore about your order. Sometimes mistakes are made and whoever packed your order didn't notice that you ordered 2 packs of carefresh and accidentally shorted you. I've had it happen to me and I've accidentally done it to others in my business.
Those bird cups are fine to use. I use them for evacuation purposes in my carriers and cages. The food/water dishes that usually come with those carriers are too shallow and all the food/water spills out. The bird cups can be securely attached to the bars of the cage or door of the carrier and prevent spilling.
Members here have used lots of things that weren't meant to be used for
GPs. If you get creative you can come up with some great ideas and toys.
Such as
-windchimes for toys
-bowls for hidy houses
-fleece hats for snugglies
-drainage tubes/pvc pipes for ramps
-shower organizers for hay racks
-and our all time favorite...storage cubes for cage sides and sign plastic for cage tray bottoms.
