Dear customer, thank you for your enquiry. All the promotion are managed by Qoo10, however so far we do not have any bodywash promo that is on $7.90. Usually the max promo is $9.90 for 2pcs with free shipping. As for Organist Jeju Bodywash range, it is the premium collection and also bigger in capacity (750ml) as compared to ON the Body bodywash (500ml), which is why there is a additional top up of $1.50 for this range. Being said so, for On The Body and Organist Jeju Body wash in Qoo10, it is one of the best price you can find as well, as the retail prices is selling at $14 and $20 each respectively. Thank you.
