Britney's AmEx -- Don't Leave Home, Period!

TMZ has obtained court documents filed today, which include a list of Britney Spears' American Express card expenses for the first 11 months of her conservatorship -- the highlight ... she ate at home a lot.

Miss Brit spent a grand total of $5,183.13 at restaurants. Our Britney people tell us the figure is relatively low -- for her -- because daddy Jamie is a cook and did his thing at her house most nights.

As for other expenses on the AmEx card:

Furniture: $17,370.29
Charities: $974.75 (remember, this is just her credit card -- we're told more was donated).
Merchandise, clothing, supplies and groceries: $62,252.11
Transportation/Auto: $18,959.82
Travel: $10,096.53
Communications: $2,150.41
