💡 LIFE HACKS FOR BOOK LOVERS

A few useful tips to make shopping more convenient and profitable:

• Want to add books to an order you've already placed?
  You can, if the order hasn't been sent yet. Just add the books to the cart — the "Add to order" option will appear in the "Payment" section. Pay in a convenient way (PayPal, card or online bank) — and the books will be automatically added to your order. If there is no button, it means the order has already been processed and packed. In this case, you can place a new order separately.
• Want to buy a book now and send it later with your next order?
  When placing your order, select the "Buy and put it aside (add to future order)" option. The next time you order, this purchase will automatically appear in your cart, and we will send everything in one parcel.
