I have make an order from that site too, but haven’t received my parcel yet.
I have make an order from that site too, but haven’t get my stuff.
Can I say “my stuff” for my parcel?
I have placed an order from that site too…
or
I have ordered from that site too…
in both cases.
… but haven’t had my stuff" - would be highly informal and not usually suitable.
Thanks.
