how does one place an order through internet?

Question

what are the particulars to be submitted?

Answer 1

You need to specify what you are ordering or buying?
Cannot answer this question without more information.

Answer 2

Your question is pretty general and hard to answer.

You need to do a web search for dealers who sell the item you want using an on line store.

Once at the on line store, you find the specific item and if you wish to buy it you place it in your on line cart and proceed to check out. You pay via credit or debit card.
