I recently received a $50 gift certificate to Dutch & Olga's greenhouse. I went there Saturday, 5/12/07 and it was very busy. I found 4 plants costing $10 and decided I'd wait until another day when it wasn't so crowded to choose the rest. The line was really long so the owner who was in the gift shop said to bring purchases over there "no waiting". I did and when I took out the $50 gift certificate he said He couldn't take it unless I purchased $50 or went to the other "long" line to get "change" in the form of another gift certificate. He was the owner so I don't know why he couldn't deduct the $10 from the $50 and sign his name on the certificate showing the balance. Gift cards automatically give you a balance but this was an old fashioned written certificate. I left not spending anything.
