Parcel Reminders

Hi everyone! I keep on forgetting to mention this but it is very important with the number of boxes I picked up at the postoffice. If anyone is sending me a parcel or bag that weighs more than 5 kilos, can you please ask the person who processes your item to put a "heavy" sticker on the parcel or bag? AusPost does have this sticker in orange color I think. This will give me an idea that the box or bag is heavy and thus avoid injuries. I think this is not too much to ask and wont cost a cent to ask the person behind the counter. Thank you.
