<prompt> Human: I was thinking of buying things from eBay or aliexpress that could be profitable or something like that  <response>: Buy the next bigger quantity of your normal household items. Anything that you use normally. Invest in saving money.Toilet paper in the 4 roll pack is 3 cents per sq ft. Get a 12 pack and the price falls to 2c sqft. Thats a 33 return in one week.Buy a coffee maker and a nice travel mug that you enjoy drinking from, brand-name coffee, even some fancy flavored creamer if thats your thing. Then your 4 starbucks turns into 50 cents each morning, for an 87 return every day.Buy a case of 24 bottled water for 4, instead of each bottle 2 at lunch. Thats a whopping 92 return in one month.Dont seek out things that are a good deal or on sale just because. Only the items you have already bought in the last month. You could easily turn your 50 into 100 in savings by this time next month.
