Recommendations for most affordable artificial flowers in bulk?

Michaels has the best deals. Especially if you're on their rewards program. You get coupons and "money" to spend there. I've bought most of my flowers from there and have save a lot of money. I bought the greenery from Amazon though because it was cheaper

Joann is cheapest for silks.

90% of my flowers are from Jo-Anns, and the remainder from Factory Direct Craft and Efavormart.

I hit Hobby Lobby for flowers & ribbons.

I was just in JO-Anns yesterday and they had a buy one get two free. I didn't look when the sale was ending but worth a look again.

We used Budget Bride, and we really liked them.

Here is my bouquet:

I got mine at Hobby Lobby. One of my sister-in-law's and I made the bouquets for the wedding with flowers we got from there.
