Sem eden izmed tistih kupcev, ki so narocili produkte, katerih ni bilo na zalogi. Po dveh tednih se vedno ni bilo ne obvestila ne narocenih produktov, telefonski pogovor ni obrodil sadov, se je pa zacelo premikati po poslanem emailu. Samo 3 stars dajem zaradi slabega obvescanja glede dobavnega roka, sicer so produkti tako kot opisano na stranen, poslani v dobri embalazi, ki preprecuje poskodbe.
