Is it just me or does Maritz have some of the worst organized gas station shops? There's always 15 different documents to download, some of that is updates (why didn't they go to the original guide and update it there?) and then the questions that you print out often aren't the same ones you have to input into the computer.
When I was a new shopper it was quite difficult to wrap my head around this. I like shopping for them because they have a lot of jobs in my area and sometimes have great bonuses but if I sit down and think about it their system is really a hassle!
I can't ever seem to get assigned any of these even though I've done some hardware shops galore for them
If you have done hardware shops galore you should be able to self assign? Take any gas stations they have on the board to show you can do a good job. Many of their gas stations are offered to proven shoppers in routes to bid on. So you may not see most of them. However, two of their clients still don't go the route option so just start taking some off the board at base pay. That will get your feet wet and you may get offered a route or two if you do a reasonably good job.
