Is a straight forward, I have no discounts and no shipping, the only thing i see is that I have prices over the 1000. I check with paypal and there's no limit with them but if I try to charge anything over 2,999 i get this error. .this is the link: https://www.alim2016.com/inscripcion-expositor.php at the end of the page you can see the add to cart, just have to choose a Exhibitor booth the model and the location and it will thell you the price. when i have it in the shopping cart and do a checkout i get the error.
