"It's just a prank, bro" were the words a particular wizard/mage/etc. had heard a few too many times. Even more aggravating because April was in fact a woman. Somewhere between practicing magic and getting harassed by siblings, roommates, or a co-worker who really needed to be more professional April snapped and gave up trying to be some well known magic user or abusing her powers in the mundane world to have a small fortune with little effort. She instead abused her powers in the mundane world to eek out a living, and run her store "April's Fool" Using all the magic store traditions of appearing in places where it shouldn't, having some stalls on the side of the road or in a dark alley, and even having an online store that would appear to a few people "coincidentally".
At first it was just giving other women/girls some tools to prank their harassers back with maybe a little interest, but it evolved as she just embraced the pranks allowing some clever but mischievous people to have some special items. It was technically open year round, but she really only went out of her way to deliver some magic items on April 1st. Well near the end of March 31st since you needed to plan sometimes.
The only real contract April made people sign was "You will not cause any lasting harm. Any emotional damage caused you must deal with personally." Having fun was all well and good, but she believed you should clean the messes you caused.
