Randy:
First of all, you've mentioned a couple of times that some inexperienced people here are giving bad advice in this board. So let me start by saying that I am not an experienced florist at all; in fact, I don't actually consider myself a professional florist. 10 years from now, maybe, but not now.
What I am, however, comfortable doing is to analyze a situation quantitatively. That's actually what I'd been doing in my entire professional life. In fact I am so good at it that sometimes I even get it right (most of the time, I don't). I tend to believe that my analytical skills are good enough to irritate experienced pros like you, Cathy, BOSS, many others here.
So here we go...
Wire orders may provide enough revenue to sustain a florist, especially if the florist resorts to cheating, but robs them of future potential to flourish and succeed.
It could, depending on how much the wire-in sales would dilute the store brand. Filling for WS.com orders would dilute store brand; that's the way I look at it. Brand-dilution would result in the decrease of growth potential.
So the question to me is relative...
If a $1M-revenue shop is expected to grow 10% (100K) a year, 1% reduction in growth would "cost" them $10K. So it's obviously stupid for them to try to earn 5K from wire-ins, if doing so leads to the loss of 10K growth.
But if the brand wasn't hurt by filling wire-ins, then any positive earning is a good thing. At least that's the first approximation with everything else being equal.
For a business like yours and Cathy's, sales of wire-in products (especially cookie-cutter arrangements) would significantly dilute your store brand. The dilution would be so great that no achievable amount of wire-in revenue would be able to compensate the loss. That's my prediction.
But I think that's not universal. I think there are different kind of shops, which are smaller and whose brands are more generic than Oberer's or Avante Gardens'. Many of these shops are already serving the kind of arrangements similar to WS.com orders. For these shops, brand dilution due to filling wire-ins is much smaller than it would be in your kind of shops.
That is, the "damage" by brand dilution would be smaller in these small generic shops. It is possible, although not certain, that the wire-in earning could outweigh the possible loss of growth potential.
Now tell me I am completely wrong.
