Thanks. That Tidewaterice.com is pretty cheap.
We need at least 14 pairs.
I've purchased tights (and other things) from tidewaterice.com several times with no problems. (I have twin DDs who wear the same size, so buying even 2 pair/skater gets the lower price.) They carry the "light tan" Mondor Evolution OTB tights (#3338) with the fastclips that my kids prefer. I like the buckles - when we had velcro or hook-and-eye OTB tights, they got snagged on the fasteners a lot. (Tip: after lacing up, put clear packing tape around the hooks and laces so the tights don't get caught/ripped.)
You could contact them to ask if you could get a "team discount."
The ISI sells USicewear tights to fund the ISIA Education Foundation. (Scholarships for skaters)
