Do not buy flowers from Costco for any occassion!
I ordered two kinds of flowers in bulk from Costco for my wedding. We had purchased the vases to place the flowers in. I was on my way to pick up the flowers on the Friday before my wedding. I contacted Costco flower department to let them know I was on my way. She told me the flowers did not get delivered from "Native Flowers" and that I needed to come up with some back-up flowers.
A courtesy phone call in advance would have been nice. The florist at Costco (the Manassas-Virginia Costco) provided the worst customer service. She did not respond to phone calls or e-mail inquiries. I should have gotten a cue when I had to wait for an hour to speak to her even though I had in fact made an appointment.
