Best wholesale bulk flowers?! I need to order!!

I was wondering what you ladies suggest for the best prices on wholesale bulk flowers.  I'm 95% sure we're just going to order them from costco, but any other experiences wold be great! My wedding is coming up very soon and I need to get ordering the flowers out of the way so I can relax.  It's the last big thing I have left to do! Also, if I order them so I can make my own centerpeices, how many days before the wedding should I have them delivered? My rehearsal is two days before the wedding and the night before the wedding my stepdaughter has a dance performance at school and I'm a little nervous about getting everything done in the last couple days before the wedding. Yikes!

I have used samsclub.com and globalrose.com and was happy with both. Sams Club is where I got my roses and hydrangeas for my wedding. They had by far the best price...even better than my florist's cost. And I used globalrose.com to order roses to use on a cake. They were fantastic.

I too have ordered from Sams Club for a party and was extremely pleased with them.

Do I have to be a member of Sam's Club to order from them? We'er members with Costco but Sam's has better prices for flowers...

You do have to be a member, but the membership fee is so worth it!

We are also ordering our wedding flowers from Sam's Club! =) 

We ordered from sam's club and was very pleased!
