Not tested since I didn't have the latest CSV file
You'll have to adjust this a bit I'm sure, but the idea is to delete the " STALE" from the entries in col 3 of the CSV sheet and then continue by replacing stores with TRUE so that SpecialCells can delete them easily
'delete stores
Call .Columns(3).Replace(" STALE", "", xlPart) ' in CSV file <<<<<<<<<<<<<<<<<<<<<<<<<<<<<
On Error Resume Next
For Each rStore In ThisWorkbook.Worksheets("DeleteStores").Cells(1, 1).CurrentRegion
Call .Columns(3).Replace(rStore.Value, True, xlWhole)
Next
.Columns(3).SpecialCells(xlCellTypeConstants, xlLogical).EntireRow.Delete
On Error GoTo 0
