If Gamersgift is so reliable then any other site to buy steam gift card why are we relying on Amazon or even steam?

So I've been watching some posts and comments regarding how they're struggling with payments, including me and Amazon is giving weird loop/bug that doesn't allow anyone to buy steam gift card (from Amazon pay not the overpriced one). Then I saw some comments about Gamersgift was little bit skeptical about it at first since I never heard about them before but after some research I found that they're legit and also mentioned on steam support as one of the online retailers, so I gave it a try with 150 inr GC first which went smoothly, having an option to pay with UPI is best. Received the code instantly after the payment, included in receipt itself.

I know gift cards aren't replacement to the card payments but still worth it for frequent buyers. What are your thoughts on this?

Do any of you had negative experience on it, would love to know that too.
