I have only used Garden Grocer but I have been looking into Wego since becoming a
DVC Member.
Garden Grocer's fee is only $12 and Free if your order is over $200.
Their prices can be a little higher than Wego but atleast you know ahead of time what the price is.
You can pay GG ahead of time with a Credit card for no extra charge. WEGO charges a 3% fee for using a Credit Card.
Wego also charges an extra fee of 10% for leaving your order with Bell Services but I would tip either that much.
So you can order GG and not worry about it. You groceries will be waiting for you.
Wego's fee is $17 for orders up to $100; $22 for orders $100-$200.
BUT the prices are going to be cheaper. You can choose where to get your items.
I have heard that Marge is great to work with and they even call you if they have a question while shopping.
It would probably be better for larger orders if you want specific items like produce.
They are personal shoppers.
I think personally I will use Wego for larger orders and continue to use GG for smaller orders.
