Any feedback or constructive criticism is welcome. I'm not sure about some of the vocab I used. I wanted to say that you pay by the weight, but I have no idea how to say that. I only know 多种

My teacher gave a listen. She said the only grammar issue is using 通常 rather tgan 经常. She had also thought i had recorded it all in one go, in reality i paused the recording between every sentence, and most of the sentences did several takes.
