I am actually doing the same thing as of today! Current progress is below:
Total Parts required 5187
Parts Bought 2628
Order 1: 1510 pcs for $ 140,50
Order 2: 582 pcs for $50,00
Order 3: 18 pcs for $10,00
Order 4: 518 pcs for $32,26
So halfway there for around $250,-.
Do you have any tips on how you manage the Wanted list? I have to follow a 3 step process :
1) search for cheapest price per part
2) place the order
3) update my excel partslist sheet
4) update my wanted list on bricklink (deleting manually each item purchased)
Also would like to know if you placed many small orders to get the cheapest price per part or did you place large bulk orders?
Hope you can share some tips and tricks because sometimes its all very overwhelming when trying to find good stores!
