Cheap short run alternates?

[IAN]

Here's a cheap short run alternative:

250 one sided flexis for $475 or about £330 from Pirates Press

it was meant to say alternate!

so I want to put a bonus track in with an LP im releasing soon. but I only want 100.
any ideas how to press it cheaply? a 7" was coming up as £400+ and flexi disks look like you can only do 500 at a time.
CD isn't exactly what I want to do, would like it so you can play the album and then put the bonus track on after, without having to change format
