My future sister in law used wegmans. She went in on the Thursday before her wedding told the florist she was looking for wedding flowers and they gave her buckets to fill. Then they kept them in the cooler room for her until the next day. She and her moh did the arranging though. The florist helped her pick things that coordinated though.
I had a consultation at the Fairfax, VA one- they required me to schedule an appointment ahead of time. I tried to just show up and talk to someone and they said I had to book a time. I met with a woman and then she had me email her photos of bouquets I like. They sent me pricing for two different options- bridal bouquet $150-175, bridesmaids bouquets $50-$70, boutonnieres $20. I am actually going with a florist though, because their prices were almost the same as Wegman's (bridal bouquet was the same, bridesmaids bouquets are $10 more with the florist, and boutonnieres are $8 less with the florist) and the florist only charges $25 for delivery whereas Wegman's was going to charge $110 for delivery. I was surprised because I was really sure that Wegman's was going to be the most affordable option (for having someone do the arrangements for me- I don't have the patience or time to arrange my own flowers the day before or day of).
