Google checkout memory limit help

[matchett64]

Ok so heres the problem......

Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 244 bytes) in /includes/modules/shipping/table.php on line 179

Now I know there are a million and one post on this, most saying that this is an issue I have to take up with my "hosting service" or have access to "php.ini" i understand all that but my host will not increase this size of my memory!!!
Would jump ship if it were not for the fact that i have alot of sites hosted with and it would just take too much hassle to sort!

They will not allow me to create my own php.ini or allow me access to it, they run php as cgi scripting by the way.

So this is my problem, i want to install google checkout as alot of my customers are requesting it and it goes well getting refunds from my adwords account......

I know there is a way round this by code similar too

ini_set('memory_limit', '8M'); 

But it is just illuding me where to place this code in the file to allow me to run the script........will probably kick myself with that answer but any help would be great!!
