Здравствуйте!Я понимаю, но к сожале

Здравствуйте!
Я понимаю, но к сожалению я никак не смогу использовать присланные мне металлические устройства, они на коляску не подходят. Я бы вам их вернула, но доставка стоит дороже этих устройств. Поэтому прошу вернуть мне деньги, 1$ это мало.

Hello,
I understand, but unfortunately I will not be able to use all my metal devices, they do not fit the stroller. I would have them back to you, but shipping is more expensive of these devices. So please give me back my money, $ 1 is enough.
