FYI to protect your donated items from getting wet if it rains

Good Day everyone! With the unpredictable weather we are having these days, can I please request dress donors to put their donated items, if possible inside a plastic bag (like grocery bags) before putting them in a box or satchel. If there is nobody home, the postman just drops the parcel inside the gate and there is nothing to protect the parcel if it rains.This way, if the dresses are protected by a plastic bag they do not get wet if it rains even if the external packaging gets wet. Hoping for your understanding. Thank you.
