Tarne ja tagastused

1. Tavaline kohaletoimetamine järgmisel tööpäeval (Madalmaad). Teistesse riikidesse võib kohaletoimetamine võtta kauem aega – mõnikord tuleb tellimuse kättesaamist veidi kauem oodata, kuid see on alati seda väärt!
2. Tagastamine: saatke meile e-kiri või helistage, et saada oma RMA-number. Ilma RMA-numbrita ei saa me raha tagasi maksta.
