Was sent to me by a Ukrainian colleague that I would trust. Ideally you have to send using direct transfer I think. The details for that are on that same page.
That money is likely to be used for immediate expenses of army like salaries, fuel sandbags and anything that can be useful in fighting. Javelins are provided by other countries for free.
Beside the political aspect of it, which is fine by me, this is actively meddling in foreign conflicts. One thing is to express support for one side, but I believe there are other better channels to get involved militarly.
Edit: also if our governments cared as much as keep telling us they do, they would take care of funding ukraine themselves. We wouldn't still be relying on private initiative, which sounds ridicolous to me.
