As we only provide ONE chance of exchange for every order, we highly recommend sending the package via registered mail as we would not be responsible for any lost mail sent back through non-traceable mailing options.

Please contact us BEFORE mailing the items out as we would need to check if the item that you wish to exchange for is available. bYSI® Online Store will not process your exchange if you did not notify us in advance.

bYSI® Online Store will only accept exchanges for the same item of different size/color, or another item at the same value. Please be aware that returned items must be in the same condition with the price tags in which you’ve received them and MUST be in excellent condition (unworn, unwashed and unaltered). Upon receiving your package, we will inspect the condition of the items before proceeding to do exchange/refund. In such cases, the delivery or return expenses will not be reimbursed. Do note that bYSI® Online Store does not accept returns sent carriage due to cash on delivery. Customers who wish to exchange their online purchases or process their refund at our retail outlets will not be entertained as purchases made via our online store can only be returned online.



You may request for a refund if the items are sold out upon your order is received. Kindly allow 2-4 weeks working days to process your refund accordingly and the duration may take longer depends on the bank processing.
