I ordered bedding from Achica.
When it finally arrived they weren't suitable so I returned them. Achica's policy is the customer pays return postage.
Because my items were heavy (super King duvet, pillows, bed linen) the return postage was £15!!!!
I sent via Hermes but the weight plus extra insurance to cover the order value really pushed up the costs.
Out of curiosity I googled my items and not only did I find them cheaper elsewhere, these companies offered free returns.
Nowadays, most online sellers offer a prepaid return system. Achicas items are not such a bargain that they can opt out of this service.
