Shipping
Shipping rates are calculated at checkout based on your shipping address and the weight of your order. Please allow a processing time of 2 business days before your shipment is dispatched
Delivery
Expected time taken to dispatch the items is given against each product on the respective product details page. While we will try our best to dispatch products as soon as possible however in unusual circumstances the delivery of the products may take up to 7-15 days approx as per local guidelines.
In the unlikely event that we are not able to deliver your order completely, we shall cancel the remaining undelivered part of the order, and send an email to you informing about the same. In such cases, your payment against the undelivered part of the order shall be refunded, in the manner the payment was made
If your order has multiple items, these may ship from different locations in separate shipments. You will receive an email if the shipment does not contain all the items that you had ordered.
We work hard to ensure that we meet our delivery estimates, but occasionally there may be delays that are beyond our control. In such cases, we will do our best to keep you informed and provide you with the latest updates on your order delivery status.
