(VLOOKUP) Merging Two Sheets with Common Column A Values

I have 1 XLS file, which contains two sheets.

SHEET1:
A: PartNumber
B: Price

SHEET2:
A: PartNumber
B: Price

Sheet1 has data for both PartNumber (A) and Price (B), but Sheet2 only has PartNumbers (A) and Price (B) is an empty column.

I am trying to populate Col B in Sheet2 with prices, where Sheet2-A matches Sheet1-A.

NOTE: All columns have a header (A = PartNumber and B = Price).

SAMPLE OF WHAT I'M WORKING WITH:

Sheet1:
PartNumber | Price
06255-PVJ-315 | 100
06255-RGL-305 | 20.45
06255-RGR-315 | 40.35

Sheet2:
PartNumber | Price
01464-XVJ-000 |
01864-XRJ-000 |
01564-XGJ-000 |

( | serves as a column separator, in my sample)

There are thousands of rows on each sheet.
