[Note: I have posted this identical question as a comment in the "Soil for VFTs" section of the website]
My particular situation was not covered in your (very informative) website's FAQ section, so I have a question for you.
After searching for some time for perlite, I resorted to purchasing the "Desert Sand" product variety by Mosser Lee. I have read dissenting opinions about using this type of sand in a soil mixture (part Desert Sand, part Sphagnum Moss) for potting a VFT.
From what I've researched, the ideal soil conditions necessary for the flytrap's survival contain sand that has a) a neutral PH and b) does not contain any salts.
If you aren't sure if desert sand is specifically not recommended, would you happen to know what it contains?
My VFT has arrived in a baggie, and I fear it will die if I don't pot it soon!!
I look forward to hearing back from you! Thank you very much for your time.
