How to apply more than one adverb to a verb


> 無料か **安いお金で** 食べることができます。  
>  You can eat for free or _with cheap money_ /cheaply.

I'm finding 安いお金 a bit strange. If I wanted to say "You can eat for free", I'd
write:

> 無料で食べることができます。

If I wanted to say "You can eat cheaply", I'd write:

> 安く食べることができます。

Are these both correct?

安いお金で reads to me like "with cheap money". I'm guessing you have to do this
because

> 無料でか安く食べることができます。

is ungrammatical (at least it looks ungrammatical to me). It's hard for me to
see how you would get from 安く食べる to 安いお金で食べる. Is there are more general
grammatical transformation going on here, or is it just specific to this
example. If there's a more general principle, could you give some other
examples please?

Maybe my most general question is how do you say

> (adverb A) or (adverb B) verb e.g.  
>  Run quickly or slowly ( _you'll still get there in the end_ ).

or maybe that's totally unrelated to the problem above. Sorry for rambling.




First, you seem to be concerned about the validity of 安いお金 itself. In my
opinion 安いお金 should be avoided if you write something professionally, but as a
matter of fact it's sometimes used by native speakers. BCCWJ has two instances
of 安いお金で. Semantically it just means the same thing as 安く. Another way to say
this is 安価に.

So 無料か安いお金で is "無料で or 安いお金で", or "either free or at a low price". This で
marks both 無料 and 安いお金 at the same time (an example of [right-node
raising](https://japanese.stackexchange.com/q/17743/5010)). You can also
explicitly use two で and say "無料であるいは安いお金で". Of course you can say
"無料で、あるいは安く食べられます" and "無料で、または安価に食べられます", too.

The direct combination of でか (i.e., "無料でか安いお金で", "無料でか安く") is slightly clumsy
to me, although perfectly understandable.
