Buy / Purchase table

• I have bought this table.
• I have purchased this table.

What is the diff. between buy and purchase.

Hi
This is mainly a matter of register. In English we have many words which are pretty much synonymsbut often one sounds more formal than the other.

In this case "bought" sounds more every-day than "purchased". They are both useable but I'd tend to use "bought" in a chat with a pal and "purchsed" in a formal letterespecially a letter of complaint!

I dont think there is any difference. Just two ways of saying the same thing. However I would say them like this -

I bought this table
I purchased this table

I would leave out the "have"

I agree with Suzi br
