Ever wondered why speakers, amplifiers, projectors etc. come with a slightly heftier price tag in India compared to their overseas counterparts? Well, part of the answer lies in our country's Goods & Services Tax (GST).

But here's the kicker: Don't let that GST input slip through your fingers! Especially when some of the products we supply carry a GST rate of 18% and 28%.

At AVStore, we provide you with a GST compliant invoice for every purchase.

Simply put in your GST number during the checkout to avail an offset.
