Does the shop combine shipping? Does the shop admit refund?

Yes, we work within weight ranges according with the rates of National Spanish company CORREOS. Thus unfortunately shipping one CD only cost the same than shipping up to four because in Spain there's only one  range for shipping from 100g to 500g and the cds weight around 120 grs each. But of course if you purchase different items the weight combines being cheaper. Thus consider to purchase multiple items each time. It really woth. All shipping are tracked and shop  shipping policies can be read explained in detail here. We ship within 24-48 hours after order is placed and we do not refund once the item has been shipped. By default shipping is certified so you can track it down.
