Being an Indian I do not really expect much, if you say you will come in between 10 am -12 noon I will wait for you till 1 or 2pm.
The Peppertap looks snazzy but the delivery/ logistics arm is extremely slow.
They were going to deliver my groceries in the 10am to 12 noon slot and I got a sms from them at 11:45 saying that all my groceries have been packed and will be at my door shortly.
Being an indian I was very happily waiting at the door for them, after a few minutes I got another msg saying that I was unable to receive my groceries and that they will try again, I sent several emails tried to call them but they are to busy to respond.
Also I have found that they have changed the list of items that I had ordered. Without any notification at all.
Still havent received my groceries(in case your wondering its around 4:30pm)
Overall I would advise you to be vary of this app.
Cheers!
