pregnancy pillows -are they worth it?

[Autumn2014]

I'm normally a tummy sleeper, but now my bump has come out I can't get comfortable on my front and finding that I roll onto my back and wake my husband with my snoring! I tried wedging a spare pillow inbetween my legs but it didn't seem to help. On a wim I bought a pregnancy pillow in tk max.today and wondered if I've made an expensive mistake, so before I take it out of the package I thought I'd ask here. It one of those that can be used in pregnancy and then shows pictures of uses once baby is here for feeding etc
Rrp £50, can that be true? Marked down to 29£. Have I been fleeced?

Borrowed a Dream Genii from a friend last time and it was heaven! Couldn't justify the cost this time so got one from Aldi a couple of months ago - it's a long tube. Was about a tenner. Absolutely couldn't sleep with out one. Hard to turn over with though
