Just because they have an IT department doesn't mean then know anything about web development, so you can't fault them for lack of knowledge. Their is a very large architectural testing company I work with that has a five man IT department that builds crazy complex internal databases and software, but they don't know basic CSS. What they do and what I do are two totally different animals.
Now,
laziness for not looking it up I do fault them for. Google "paypal donation" and the PayPal website comes right up to the section on donations and has a link to show the
example code that you copy/paste.
