Merge multiple spreadsheets with common field

Hi I have two spreadsheets with a common field and I need to merge them into a separate third spreadsheet with matching data from both.

I attached an example workbook with simplified sample data.

Sheet 1 has Product_id and SKU fields. Sheet 2 has SKU and Price fields. I need to merge them into Sheet 3 so all three fields are displayed.

Unfortunately in the real data there are literally 8,000+ entries. Roughly 90% of the SKU's are in both spreadsheets, but some SKU's are in one but not the other and visa versa, so sorting, copying and pasting will not work.

I suspect I need the equivalent of IF SKU (Sheet1) = SKU (Sheet2), then print Product_id, SKU and List Price in Sheet 3, but I don't know how to do that in Excel.

Thank you very much for any help you can provide.
