I notice how you use 'Paypal' a lot and occasionally 'paypal' without any capital at all. This really bugs me as the correct usage is 'PayPal'. It's like when people type 'Youtube' instead of 'YouTube'.
To put it into perspective, you never use 'Digitalocean' or 'digitalocean' - there is always a capital D and a capital O.
I imagine this would be quite an easy change to make and would make yourselves seem more professional and consistent.
I can't see this getting many upvotes at all but it could be really easy to change (you could even Find and Replace to change things to PayPal).
