I earned a ton of points two ways- by playing the highest and easiest paying games everyday, and by reselling items in my shop. I would pick a few items every day to search the wizard for, buy the cheapest ones, and resell them. Each day, I would search those items, and maybe after a week, start searching for a little more expensive items to sell. Food items sell the best. You could start out selling omelettes and jellies along with some cheaper scary foods and gross foods, then work up. Use all your profits from sales to continue upgrading the size of your shop and buying more foods. Do not buy bigger items unless you are sure they can resell and at a decent profit.
