'Thank you for your help. I live out-of-state and wanted to send flowers for my cousin's funeral.'
'This was the easiest way to send flowers. To know with confidence they will be delivered to the correct place and quickly. The process is so convenient. Great option.'
'Everything looked very nice, from the flowers, the basket, & the hunter's orange ribbon. The woman who took my order was very pleasant & friendly. The only thing is that the flowers online were white & the one sent were yellow.'
