Im attending Equine Affair in April in Columbus, OH. Im looking forward to buying as much tack as I can (Saddle, Headstall, Breast collar, reins...etc). Would you bring Cash? Credit Card? Check? To pay for these things. I am weary of carrying alot of cash but also don't want to go home empty handed, leaving that "perfect" saddle behind! Im new at buying at expos!
