Returning Data from website but excluding certain URLs

[ScabbyDog]

On Sheet1 from column A row 2 downwards I have a list of URLs. I have the below code which loops through all the URLs and then it calls another macro which does stuff with the data it gets. However, I want to alter it so that each URL it loops through, it also pastes this URL onto sheet "URLs" in column A in the last used row. When the below macro starts and looks at the first URL to get data from it should only get the data if the URL is NOT contained within column A on sheet URLs.

Sub Start()  
  Dim i As Integer
    
  For i = 2 To 350  
 
  Dim b As String

   b = Worksheets("Sheet1").Cells(i, 1)
       
   Sheets("SHeet2").Select

    With ActiveSheet.QueryTables.Add(Connection:= _
        "URL;" & b, Destination:=Range("$A$1"))
        .Name = _
        "site.php?id=2083&brand=qf&status=RU&tipo=CALCIO&disc=CALCIO&manif=BUND_1"
              .FieldNames = True
        .RowNumbers = False
        .FillAdjacentFormulas = False
        .PreserveFormatting = True
        .RefreshOnFileOpen = False
        .BackgroundQuery = True
        .RefreshStyle = xlInsertDeleteCells
        .SavePassword = False
        .SaveData = True
        .AdjustColumnWidth = True
        .RefreshPeriod = 0
        .WebSelectionType = xlSpecifiedTables
        .WebFormatting = xlWebFormattingNone
        .WebTables = "2,3,5,6,8,9,11,12,14,15,16"
        .WebPreFormattedTextToColumns = True
        .WebConsecutiveDelimitersAsOne = True
        .WebSingleBlockTextImport = False
        .WebDisableDateRecognition = False
        .WebDisableRedirections = False
        .Refresh BackgroundQuery:=False
    End With
   
     Call DoStuffWithDataPulledFromURL
    
    Next i
  
End Sub
