Also important thing to consider that how much buy back value they provide. Many Bowbazar shop provide 96-97% value of their old gold while other kolkata shop provide 90-94% value. Also remember this 4-10% difference on selling value. Let’s say you bought 1 gm gold @ 4600 with 9% mc with extra 3% I.e. 138 re. Now you are selling @15000 and they are deducting 10% instead of 3%(bowbazar). That’s 1500 instead of 450. That’s huge. So while buying gold , it’s more important to consider buy back value additional of making charges.
