On 26th Nov, I ordered flowers and cake for delivery on 28th Nov in Mumbai.
Price was competitive and flowers and cake were delivered on 28th (Sunday) with no issues. (I paid by paypal)
Only thing to complain about is that it was very difficult to get in touch with their customer service. I read on their website FAQ that there was a lead time of 3-4 days for orders and was concerned if they would deliver on 28th with order placed on 26th, Called twice to US number given in "call" link and left messages but no body returned my call. (I still haven't heard from them)
Overall it worked out fine.
