Had a stall at a Lego market on the weekend (8:30 - 2:45) Table cost $35. Temperature 30+, no air con, only fans in a tin shed exhibition hall.
Stoked about what I sold, but I was woefully prepared for how busy I would be. I had plans to make a note of what was sold and price, but after the first half hour, this was abandoned and I focused on completing sales and keeping the tables full of product.
Went with a view to sell these larger sets: Palace Cinema, Mystery Mansion, Santa's Workshop, Winter Village Market, Deep Sea Exploration Vessel and 60004 Fire Station. Sold all but the Fire Station @ 2 x price paid. The Fire Station came home with me.
Friends sets I had purchased from Woollies on boxing day (Heartlake Gift Delivery & Heartlake Surf Shop) and Aldi Friends book and polybag sets - all sold
City sets - only sold a few small cars, eg Rally Cars, Monster Trucks
Batboat Harbour, 2015 Star Wars Advent Calendars and some Rogue One Buildables - gone
Ninjago - did not sell one set or polybag - I sell these all the time on eBay - go figure
Farewelled books with minifigs, old baseplates
My daughter and I had rebuilt a lot of sets from bulk buys over the past month and we sold 20 - 30 rebuilt sets (stocktake later will give final figures)
We sold 50+ polybags - no idea yet what was sold have to trust in the fact everything had a price sticker and was priced with a least a 75% markup on purchase price.
Next weekend I'll have to do a full stock-take and put everything away properly, as when we got home and shoved everything back into the garage, we just collapsed into the pool.
If I was to do this again:
Get some sort of display carousels or shelving for elevation on table.
I wouldn't attempt to do this without help. Miss 11 was invaluable and I was very impressed with her Maths skills and ability to make change - didn't accept a $50 without showing me first.
Bring plenty of water and deodorant.
Kids know Lego - I listened to plenty of kids tell their parents what was rare and what wasn't (Gladdens the heart).
Source more discounted Friends and Elves sets.
My table got pretty messy - I would try to make it more visually appealing - quite a few people don't like touching and looking through items.
Ignore ignorant people - the number who said Advent calendars are $35 at Big W...
