Quality and discount

The packed items like rice, dal were ok but if I order Fresh vegetables, the quality is not so satisfying. Also it would be nice if there are discounts on few products. Whenever I buy the goods I never got them for discount. I always buy for original price. Many of the times I do see discounts only for expired or about to expire products. Since I am a frequent customer of Jamoona I would recommend discounts also on the small packaged products.
I also don't understand one thing, If I buy products, I get offer codes on the very next day when the order has been delivered. If I buy 60 or 70 euros worth goods today why would I buy after 2days again? I don't understand the logic behind this.
