I have a comma question!

When using the phrase "as well as" do i put the comma before, after, or before AND after the phrase.

An example sentince is:
At the store i bought milk as well as bread.

No comma is needed in that sentence. The phrase "as well as" functions as a conjunction between individual words.
Ms. Sue is right. In a short sentence like that you don't need any commas. If the sentence were longer, though, you'd put a comma before the "as well as" -- and you might put a comma after the whole phrase if the sentence continues past the phrase.

Mostly, this depends on whether you're dealing with an essential (no commas needed at all) or a non-essential (commas needed) phrase or clause:
