OK, I'll be the first to reply....
NO!!!
But then again, we did not raise ours either. We had decided that if it went to $3.00 and stayed there for a time, that we would have to...that did not happen here.
We adjusted to the higher gas price by eliminating 1-2 stop delivery runs, some time slots and by consolidating deliveries so the vans left with more on board than they might have earlier.
I doubt that anyone that did raise them due to higher fuel costs will lower them. Most florists I know that used the higher prices as an excuse to raise delivery charges will keep them where they are, since most if not all had little complaint issues from the consumer, and face it, we're still the best deal in town...same day delivery 5-10 bucks....
When I do raise/change delivery fees, I usually do it in the summer, when biz is a little slower...and honestly...folks never notice, and if they do they do not complain.
