Guys, be careful if you bought something, and then, for some reason, decided to return the goods when returning the voucher, then when buying the next product you need to buy it for the amount indicated in the voucher. If you buy something for a different amount (less than a voucher), the difference will not return to you.
As for the delivery, in my case, everything was on time, and just as easily I returned the goods. My disappointment is associated with vouchers, I did not know about such nuances and didn't expect it.
