how can i ACTUALLY spend money on venmo..

im trying to make an online purchase with my venmo funds without linking my bank account. the site i’m using (like most sites) doesn’t take venmo, i’ve tried buying a vanilla gift card but again, no websites take venmo. i also really don’t wanna have to go through the entire process of making a venmo credit card for one purchase. is there anyway to pay with venmo for a prepaid card etc…
