well at my salon which is palmbeachtan.com i pay $49.95/month instead of $25-30 for one session.And usually most salons have a free trial for new members.I spray tan twice a week and it lasts for a week or two so every week once a week is enough.it all depends on your skin.
Clear is for fair skin if you're not tan at all.i used to tan in beds for 3yrs and even tough i used very good pricey tanning lotion and only tanned 12minutes a session i went to my derm and he told me to stop or i will have very bad damage on my skin so the spray is the safe way to go.First time i didnt get the clear,they gave me a bronzer and i ended up orange.
so when you go to your salon ask for clear no bronzer.here is a video of how it works.
