I ordered 2 OPI colors from a vendor on amazon for about $17/bottle. I haven't asked my cosmetologist friend what they cost wholesale.
Has anyone tried the really cheap ones off of ebay? like $4-$5 a bottle? I'm going to grab an "off the wall" color just to try it out, but I'd love to know if anyone has any previous experience! (since it ships from Hong Kong and they have holidays etc. then the 2 week ship time... it'll be awhile before I get to play!)
and my light - it is a 45s cure time for the colors. It is a Mini Pro:45 from Sally's with 6 - 1W bulbs. I got it for $50ish two weeks ago.
So far, I have used OPI and Gelish colors. I like the OPI better, but my technique has improved too

... where have you wonderful people been all my life! first the sparkles then the nails... *sigh*
