OK..here we go!!

I've created a marco for you.

Sub datagrab()
    Sheets("Store1").Select
    Cells.Select
    Selection.AutoFilter
    Selection.AutoFilter Field:=13, Criteria1:="=Completed", Operator:=xlOr, _
        Criteria2:="=Fabricating"
    Range("C3:C10000").Select
    Selection.Copy
    Sheets("Summary").Select
    Range("B5").Select
    ActiveSheet.Paste
    Selection.SpecialCells(xlCellTypeBlanks).Select
    Application.CutCopyMode = False
    Selection.Delete Shift:=xlUp
End Sub
Add it to a module and attach it to a button and run it.

To explain:

- It goes into your store 1 sheet
- Applies an auto filter
- Filters the status column to only show completed or fabricating
- Copies from the PO column ( C3:C10000)
- Returns to your summary sheet and pastes them into B5 downwards
- Highlights the B column and removes any empty cells so there are no gaps.

I added that last point in as you said you had 8 sheets, so there would be gaps using my above method.
But the last point removes this problem.

Just make sure you have

Selection.SpecialCells(xlCellTypeBlanks).Select
    Application.CutCopyMode = False
    Selection.Delete Shift:=xlUp
At the end of all 8.

Addtionally you may want to increase/decrease the capture range
