I've picked up about 20 of the typewriters in my collection from ShopGoodwill.
Only two were impeccably/properly packaged and shipped and one of these was a special machine that I emailed them after purchase with written details and links to videos about how to pack and ship it just to be on the safe side.
Three were dreadful disasters: one was a 40 pound standard that was dropped and the frame bent drastically (it had almost no padding materials inside the box), two were shoved into cases (one upside down and the other right side up, but neither locked into their cases properly nor with their carriage locks engaged so they both bounced around for the entire trip) and put into boxes with almost no packing material. All three refunded portions of the price and/or all the shipping costs.
Most of the remainder (all portables with cases) were packaged with a modicum of care (some packing material in the case and some outside the case with reasonable boxes) and showed up in reasonable condition.
Two of the machines were local enough that I did a local pick up to ensure better care.
Generally, it's a crapshoot, but this is also the reason why I don't spend more than $20 on any machine I get from them (except one reasonably rare German typewriter in the US and a Royal with a Vogue typeface that still came out at less than $100 because only one other person noticed its rarity in the photos).
Only one of the machines was clean as a whistle and ready to type on day one. All the remainder required serious cleanings at a minimum. Two were missing internal pieces, two had repairable drawband issues, one had dramatically bad escapement issues, and one had a destroyed mainspring that I need to replace.
Only one of the group had a platen with any life left in it. One had a completely unusable platen, but it was also relatively obvious in the photos. Most of the rest were hard, but usable.
I live in the US and typically only bid on machines that are in the top 20% of their class cosmetically.
I'll echo the thought of others that I wouldn't have a machine from them shipped directly to someone as a present unless I knew they were a tinkerer and had the mechanical ability, the facilities/tools, and desire to clean and service their own machine. Otherwise, I'd do that myself and ship it to them directly.
