I use IE7 as my browser, should be the most common. However, in the last year, I attempt to place more than one item at a time in my basket, the website does not hold the previous items. This is very frustrating and sometimes I have to try to place my order several times on different days to actually get the items ordered. The only reason I haven't gone elsewhere on the internet is because I've been a Golden Oaks customer for several years and I like the selection of Breyer Horses they offer.
