I went through this entire thread and I'm surprised that no one has mentioned parcel forwarder/ agents till now but It's mostly used by people to buy replica clothing so I can understand why.
The way it works is basically, you use the agent (cssbuy, citygobuy etc) and you place the order for whatever good you want through their website from whichever chinese website it may be.
The employees then purchase it, it gets shipped to their warehouse and you can choose to some extra services like taking pics of the product (mainly used for clothing tho, some agents don't charge some do)
After this they place your item in storage, you can either buy more items and ship it all together as one big package or ship just that one item out.
https://reparchive.com/shipping-calculator-comparison/ Here is a shipping calculator that will compare all of the agents shipping costs according to size and weight, packages that weigh more than 1kg in my opinion, is best shipped with either aramex,ems or e-ems through citygobuy or CSSBuy since these have the best rates to India
For smaller stuff that some of you guys buy here that would weigh like 100gms, the shipping calculator again suggests NLpost from superbuy (I have never used superbuy before) or china post registered air mail.
I myself have purchased a few replica shoes and it's currently being shipped but I believe these agents can be perfectly used for aliexpress, banggood (whatever chinese website that can't ship to india), heck I bought my shoes off weidian and taobao which you couldn't buy directly in India in the first place
Subreddits like r/fashionreps and r/repfamindia should give some credibility and more informational threads regarding this
And yes, they do obviously charge a fee (citygobuy exchange rate compared to CSSbuy is bad) but again what can we do, this is the only way to procure some of the goods from china.
