Question
What are good white filler flowers for a small arrangement other than baby's breath (not too costly either)?

Answer
Sorry it has taken a bit of time to respond - I haven't been on the computer until now -   

To answer your question- there are several choices of filler flowers that come in white.  See below the list of choices.  I hope that this can give you more options that can easily fit into your budget.  As for prices, it all depends on your market, where the wholesale florist has it shipped in from, and supply & demand.  

Hypericum berries
Queen Anne's Lace
Wax flower
Statice
Limoneum
Asters
