scrounging - affordable bumbag collection

haha so apparently topshop names backpacks "bumbags" - so fitting. anywhooo currently have a backpack / slouchy oversized bag fetish and did some hunting. have a tendency to just pile my whole life into a bag so roomy bags are my thing at the moment... some affordable options for under $100 :

[1] urban bowling bag, $32.80, forever 21  |   [2] canvas multi pocket backpack, $60, topshop

[3] big buddha ivy bag, $90, piperlime  |  [4] utility fashion bag, $32.80, forever 21

[5] small leather rucksack, $80, topshop  |  [6] deena & ozzy chain tote, $58, urban outfitters

[7] melie bianco multi zip hobo, $55.99, piperlime  |  [8] shabd tie-dye recycled cotton  backpack, $48, baggu

i want all of these. if i buy every single one (which i wouldn't, i promise) it would total to about... $450. 

i mean, cheap is chic, but these bags are design-wise pretty cool too... any favs? :)
