My local gave us letter shirts in our colors when we were initiated.
When we were initiated into AEPhi, we got pin boxes with the AEPhi crest.
We generally gave out t-shirts and random AEPhi stuff (pencils, cups, stickers, etc) as bid day gifts. Those who joined via COB usually got whatever we'd given the new member class from the previous formal rush.
And we always did door decorations. My freshman year, I roomed with an AXO and a Theta. It looked like a package of construction paper had exploded outside our door
