'VERY GOOD SERVICE WILL USEE AGAIN'
'I was very short on time and using your service was a great help! Thank you very, very much! 6 Stars!'
'I ordered the floral arrangement for the funeral service. I realized that I had omitted a name from the card. I called this morning to rectify the situation; I didn't hear back from the florist, so I assume "no news is good news" and the name was added. Thank You.'
