I have not tried any of them but it's a start. Also, if your local supermarket has a florist (like a Giant or H.E.B.) you can ask them about buying bulk flowers. We did that for my best friends wedding and it worked out really well!!
your florist will be able to add in a lot of hydrangeas in white and maybe pink too, this will allow them to use less roses brining down the price. you can still request enough roses to gibe the affect you want. ive seen this exact cp at flower michele and its so beautiful!!!!!!!
