I hear you loud and clear on those big national sites. They always outsource to random places and the results are hit or miss. For something professional like a thank you gift, I always go with a local business directly. I highly suggest using Fleur DAmour https://fleurdamourflowers.com/ for your delivery. They handle everything themselves and the bouquets always look exactly like the pictures online, if not better. I have used them for several corporate gifts and they always deliver right on time. They really excel at making exquisite, one-of-a-kind flower arrangements for every occasion. It makes a great impression because the packaging is very elegant. Your colleague will definitely appreciate the gesture. It is way safer than using a middleman site.
