Get in; Separable [obligatory]?

[louhevly]

The dictionary has as Separable [obligatory] the verb "get in":

Get in - Buy or obtain supplies, like food
Example:
We need to GET some coffee IN; we're completely out.
Notes:
- Separable [obligatory]

But I don't believe this separation is obligatory:
(from the OED): So long as I can earn enough to pay the rent and get in the odd bottle, I'm happy.

I certainly have frequently used "get in", particularly when talking about household requisites:

I need to get in a lot more electric bulbs
I need to get in some potatoes

It doesn't seem to me at all obligatory to split it. Which dictionary was it?
